Bash Shell Temporarily Disable an Alias by Vivek Gite on March 13, 2009 in BASH Shell, CentOS, Debian / Ubuntu, FreeBSD, Linux, RedHat and Friends, Suse, Troubleshooting, Ubuntu Linux, UNIX I've couple of shell aliases defined in ~/.bashrc file. How do I temporarily remove (disable) a shell alias and call the core command directly without using unalias command under a bash shell on a Linux or Unix-like systems? An alias command enables a replacement of a word with another string. It is mainly used for abbreviating a system command, or for adding default arguments to a regularly used command.It is Tutorial details also useful for creating your own commands on a Linux, OS X, FreeBSD, Difficulty Easy (rss) OpenBSD, Ubuntu/Debian/Red hat/CentOS/Fedora and Unix-like operating Root privileges No systems. Requirements None Estimated completion time 2m Display currently defined aliases Type the following command: $ alias Sample outputs: alias cp='cp -i' alias dnstop='dnstop -l 5 eth1' alias grep='grep --color' alias l.='ls -d .* --color=tty' alias ll='ls -l --color=tty' alias ls='ls --color=tty' alias mv='mv -i' alias rm='rm -i' alias update='yum update' alias updatey='yum -y update' alias vi='vim' alias vnstat='vnstat -i eth1' alias which='alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde' alias vnstat='vnstat -i eth1' Creating an alias Create an alias called c for the commonly used clear command, which clear the screen: $ alias c='clear' Then, to clear the screen, instead of typing clear, the user would only have to type the letter c and press the [ENTER] key: $ c How do I disabled alias temporarily? An alias can be disabled temporarily and the core command get called directly. Just prefix command with a backslash. Create an alias called vnstat: $ alias vnstat='vnstat -i eth1' $ vnstat Sample output: Database updated: Fri Mar 13 15:30:01 2009 eth1 received: 158.48 GB (20.9%) transmitted: 599.82 GB (79.1%) total: 758.30 GB rx | tx | total -----------------------+------------+----------- yesterday 2.83 GB | 10.90 GB | 13.73 GB today 1.92 GB | 7.31 GB | 9.23 GB -----------------------+------------+----------- estimated 2.97 GB | 11.28 GB | 14.25 GB Now disabled vnstat alias temporarily, enter: $ \vnstat Sample output: rx / tx / total / estimated eth1: yesterday 2.83 GB / 10.90 GB / 13.73 GB today 1.92 GB / 7.31 GB / 9.23 GB / 14.24 GB eth0: yesterday 655.05 MB / 2.02 GB / 2.66 GB today 438.01 MB / 1.43 GB / 1.86 GB / 2.86 GB Another option is to type full command path: $ /usr/bin/vnstat But, how do I unalias permanently? Update your shell configuration file like ~/.bashrc and remove required alias: $ vi ~/.bashrc $ unalias nameHere $ unalias vnstat $ source ~/.bashrc Bash Shell: Ignore Clear all Linux / Aliases and Ubuntu Set User Find out if shell How do I use shell UNIX bash shell Functions When Profile Under Bash command is aliased aliases under Linux? aliases Running A… Shell or not Pass Command Line Arguments To a Bash Alias Command Tweet itFacebook itGoogle+ itPDF itFound an error/typo on this page? { 20 comments… add one } techfun March 13, 2009, 8:55 pm When you said: alias p='clear' I think you meant: alias c='clear' Reply Link nixCraft March 13, 2009, 9:04 pm Thanks for the heads up. Reply Link techfun March 13, 2009, 9:09 pm No problem, I do that kind of thing all the time myself. :) Reply Link Tim March 14, 2009, 10:48 am You can also use `command’. If you have ls aliased to `ls -lh’, command ls will run the ls command as if there was no alias. Reply Link Topper March 14, 2009, 11:24 am Also, you can see all the aliases from .bashrc or .bashcompletition or something else with # alias TAB This will list all the aliases Reply Link Michael Wagner March 14, 2009, 3:03 pm You can temporarily disable it via \ or with the full pathname of the command. Michael Reply Link Michael Wagner March 14, 2009, 3:04 pm Sorry, the output was not correct. You can put an \ before the alias. Reply Link Michael Wagner March 14, 2009, 3:06 pm Sorry, the output was not correct. You can disable it when you put a \ before the alias. Michael Reply Link Topper March 14, 2009, 7:43 pm Exactly – this was the meaning of author’s post! Did you read it ? Reply Link Michael Wagner March 14, 2009, 8:50 pm Yes I read the post but I thought it was a question not a statement. Sorry for the misunderstanding. Reply Link Aditya March 15, 2009, 6:42 am How about unaliasing? say I’ve a few aliases defined in my ~/.bashrc and ls is one of them: alias ls=’ls -alhF’ so on prompt to disable it temporarily I will say: > unalias ls and done……how about this solution? Reply Link Topper March 15, 2009, 8:45 am unalias [-a] [name …] Remove each name from the list of defined aliases I think that will be removed permanently. Reply Link Jeremy February 16, 2012, 2:14 pm yes and no. IT does remove it permanently, however, the alias is normally generated from the .bashrc or some other file that is read in during login or opening a new terminal. So technically it is not removed permanently unless the alias commands are removed from those files as well. Reply Link VoidFox June 24, 2015, 12:53 pm thanks just what i needed :> Reply Link Rory Browne March 16, 2009, 12:11 pm There seem to be some useful tips here – I usually do something like /bin/rm to avoid the rm -i alias. Of course you can always use the -f argument with cancels out -i. Another thing you could do ( if you wanted to use an unedited version of the command ) would be to start up a sub-shell. Something along the lines of…… bash unalias ls ls exit When you exit back out to the parent shell, your unalias is forgotten. Reply Link Kristian April 14, 2009, 4:24 pm Doesn’t control-L clear the screen? Reply Link nixCraft April 14, 2009, 5:54 pm This is not about clearing screen. It is about disabling aliases. Reply Link Topper April 14, 2009, 5:46 pm Yes it is ? Reply Link Jeremy February 16, 2012, 2:10 pm Although -f cancels out the -i for rm, it does not for cp. I found this page looking for a way to temporarily disable an alias because the -f isn’t working. The script will run, but the new file is not copying over the old one. During testing, I notice its because the -f I put on the command is not actually canceling out the alias which uses the -i and its still prompting for confirmation to move the file over. Reply Link nixCraft February 16, 2012, 2:31 pm Use full path or \ syntax: # skip it /bin/cp -f foo bar # OR \cp -f foo bar Reply Link Leave a Comment Name * Email * Comment Submit Next FAQ: Linux Uninstall VMWare Server Software Previous FAQ: Postfix Configure Multiple ISP Client SMTP Authentication To search, type and hit enter Featured Articles: 30 Cool Open Source Software I Discovered in 2013 30 Handy Bash Shell Aliases For Linux / Unix / Mac OS X Top 30 Nmap Command Examples For Sys/Network Admins 25 PHP Security Best Practices For Sys Admins 20 Linux System Monitoring Tools Every SysAdmin Should Know 20 Linux Server Hardening Security Tips Linux: 20 Iptables Examples For New SysAdmins Top 20 OpenSSH Server Best Security Practices Top 20 Nginx WebServer Best Security Practices 20 Examples: Make Sure Unix / Linux Configuration Files Are Free From Syntax Errors 15 Greatest Open Source Terminal Applications Of 2012 My 10 UNIX Command Line Mistakes Top 10 Open Source Web-Based Project Management Software Top 5 Email Client For Linux, Mac OS X, and Windows Users The Novice Guide To Buying A Linux Laptop … Follow +1 + 179,856 Follow @nixcraft ©2000-2015 nixCraft.

The shell is the wrapper around the system: a communication means between the user and the system The shell is the manner in which the user can interact with the system through the terminal. The shell is also a script interpreter. The simplest script is a bunch of shell commands. Shell scripts are used in order to boot the system. The user can also write and execute shell scripts. Shell – p. 3/55 Shell - which shell? There are several kinds of shells. For example, bash (Bourne Again Shell), csh, tcsh, zsh, ksh (Korn Shell). The most important shell is bash, since it is available on almost every free Unix system. The Linux system scripts use bash. The default shell for the user is set in the /etc/passwd file. Here is a line out of this file for example: dana:x:500:500:Dana,,,:/home/dana:/bin/bash This line means that user dana uses bash (located on the system at /bin/bash) as her default shell. Shell – p. 4/55 Starting to work in another shell If Dana wishes to temporarily use another shell, she can simply call this shell from the command line: [dana@granada ˜]$ bash dana@granada:˜$ #In bash now dana@granada:˜$ exit [dana@granada ˜]$ bash dana@granada:˜$ #In bash now, going to hit ctrl D dana@granada:˜$ exit [dana@granada ˜]$ #In original shell now Shell – p.

    HP BIOS Configuration Utility FAQ

    Technical white paper HP BIOS Configuration Utility FAQ Table of contents Feature updates ............................................................................................................................................................................ 2 Common questions ....................................................................................................................................................................... 2 For more information ................................................................................................................................................................. 12 Feature updates Version Features 4.0.2.1 Changes config file keyword to BIOSConfig. Changes commands from /cspwdfile and /nspwdfile to /cpwdfile and /npwdfile to match HP SSM. Adds /Unicode command to query if a system supports a Unicode password. Removes BIOS user commands. Maintains backwards compatibility. 3.0.13.1 Allows only one /cspwdfile command. Adds /WarningAsErr command to include warnings in the final BCU return code. 3.0.3.1 Changes commands from /cspwd and /nspwd command to /cspwdfile and /nspwdfile to read passwords from encrypted files created by HPQPswd.exe 2.60.13.1 Adds additional return codes when encountering WMI errors. 2.60.3 Add /SetDefaults command to reset BIOS to factory default. Supports configuration file comments. Common questions Q: The BIOS Configuration Utility (BCU) is an HP utility, so why it does not work on some HP platforms? A: BCU is a command-line utility for controlling various BIOS settings on a supported HP notebook, desktop, or workstation system. It requires a BIOS that supports HP WMI Namespace within the BIOS. HP began integrating CMI/WMI support directly into the BIOS during approximately 2006–2008 for managed business systems, which did not include consumer-based systems or entry-level units. If the system BIOS does not have the required WMI support, BCU does not work. This is not a failure of BCU. It is a limitation of the system BIOS that does include WMI support in the BIOS code.
