  • Chapter 4 Programming in Perl
    Chapter 4 Programming in Perl 4.1 More on built-in functions in Perl There are many built-in functions in Perl, and even more are available as modules (see section 4.4) that can be downloaded from various Internet places. Some built-in functions have already been used in chapter 3.1 and some of these and some others will be described in more detail here. 4.1.1 split and join (+ qw, x operator, \here docs", .=) 1 #!/usr/bin/perl 2 3 $sequence = ">|SP:Q62671|RATTUS NORVEGICUS|"; 4 5 @parts = split '\|', $sequence; 6 for ( $i = 0; $i < @parts; $i++ ) { 7 print "Substring $i: $parts[$i]\n"; 8 } • split is used to split a string into an array of substrings. The program above will write out Substring 0: > Substring 1: SP:Q62671 Substring 2: RATTUS NORVEGICUS • The first argument of split specifies a regular expression, while the second is the string to be split. • The string is scanned for occurrences of the regexp which are taken to be the boundaries between the sub-strings. 57 58 CHAPTER 4. PROGRAMMING IN PERL • The parts of the string which are matched with the regexp are not included in the substrings. • Also empty substrings are extracted. Note, however that trailing empty strings are removed by default. • Note that the | character needs to be escaped in the example above, since it is a special character in a regexp. • split returns an array and since an array can be assigned to a list we can write: splitfasta.ply 1 #!/usr/bin/perl 2 3 $sequence=">|SP:Q62671|RATTUS NORVEGICUS|"; 4 5 ($marker, $code, $species) = split '\|', $sequence; 6 ($dummy, $acc) = split ':', $code; 7 print "This FastA sequence comes from the species $species\n"; 8 print "and has accession number $acc.\n"; splitfasta.ply • It is not uncommon that we want to write out long pieces of text using many print statements.

  • Tcl/Tk for Xspecta Michael Flynn Tcl: Tcl (Ie Tool Command Language)
    Tcl/Tk for XSPECTa Michael Flynn Tcl: Tcl (i.e. Tool Command Language) is an open source scripting language similar to other modern script languages such as Perl or Python. It is substantially more powerful than UNIX/LINUX/POSIX shell script languages such as the Bourne Shell (sh), the C Shell (csh), or the Korn Shell (https://en.wikipedia.org/wiki/Shell_script). Tcl and its associated graphical user interface toolkit, Tk, were developed by John Ousterhout of the University of California. Ousterhout's group subsequently continued development of Tcl/Tk while at Sun Microsystems and later at Scriptics. Continued development is now done by an open source project team. The language has been popular for developing graphic applications and is available as public domain software for almost all computer systems (Linux, Windows and MacOS). Installation: Tcl/Tk software can be found at: http://www.activestate.com/activeTcl Binary Windows installers are available from this site for both 32 and 64 bit systems as a Free Community Edition. The lab modules were last validated with Version 8.6.4.1 but more recent versions should not be problematic. Unless Tcl has already been installed on the system being used, download and install the software from ActiveState. The installer should be run with administrative privileges. On Windows7, you should right click and 'run as administrator'. Installing with elevated privilege will allow the registry changes that map Tcl extensions and will configure the un-installer database, making later removal of ActiveTcl easier. The ActiveState default installation directory is C:/Tcl. During the installation, the installer will ask if you want this changed.

  • Bash Crash Course + Bc + Sed + Awk∗
    Bash Crash course + bc + sed + awk∗ Andrey Lukyanenko, CSE, Aalto University Fall, 2011 There are many Unix shell programs: bash, sh, csh, tcsh, ksh, etc. The comparison of those can be found on-line 1. We will primary focus on the capabilities of bash v.4 shell2. 1. Each bash script can be considered as a text file which starts with #!/bin/bash. It informs the editor or interpretor which tries to open the file, what to do with the file and how should it be treated. The special character set in the beginning #! is a magic number; check man magic and /usr/share/file/magic on existing magic numbers if interested. 2. Each script (assume you created “scriptname.sh file) can be invoked by command <dir>/scriptname.sh in console, where <dir> is absolute or relative path to the script directory, e.g., ./scriptname.sh for current directory. If it has #! as the first line it will be invoked by this command, otherwise it can be called by command bash <dir>/scriptname.sh. Notice: to call script as ./scriptname.sh it has to be executable, i.e., call command chmod 555 scriptname.sh before- hand. 3. Variable in bash can be treated as integers or strings, depending on their value. There are set of operations and rules available for them. For example: #!/bin/bash var1=123 # Assigns value 123 to var1 echo var1 # Prints ’var1’ to output echo $var1 # Prints ’123’ to output var2 =321 # Error (var2: command not found) var2= 321 # Error (321: command not found) var2=321 # Correct var3=$var2 # Assigns value 321 from var2 to var3 echo $var3 # Prints ’321’ to output

  • 16.5. Getopt — Parser for Command Line Options — Python V2.6.4
    Navigation • index • modules | • next | • previous | • Python v2.6.4 documentation » • The Python Standard Library » • 16. Generic Operating System Services » 16.5. getopt — Parser for command line options¶ This module helps scripts to parse the command line arguments in sys.argv. It supports the same conventions as the Unix getopt() function (including the special meanings of arguments of the form ‘-‘ and ‘--‘). Long options similar to those supported by GNU software may be used as well via an optional third argument. A more convenient, flexible, and powerful alternative is the optparse module. This module provides two functions and an exception: getopt.getopt(args, options[, long_options])¶ Parses command line options and parameter list. args is the argument list to be parsed, without the leading reference to the running program. Typically, this means sys.argv[1:]. options is the string of option letters that the script wants to recognize, with options that require an argument followed by a colon (':'; i.e., the same format that Unix getopt() uses). Note Unlike GNU getopt(), after a non-option argument, all further arguments are considered also non-options. This is similar to the way non-GNU Unix systems work. long_options, if specified, must be a list of strings with the names of the long options which should be supported. The leading '--' characters should not be included in the option name. Long options which require an argument should be followed by an equal sign ('='). Optional arguments are not supported. To accept only long options, options should be an empty string. Long options on the command line can be recognized so long as they provide a prefix of the option name that matches exactly one of the accepted options.

  • Lecture 17 the Shell and Shell Scripting Simple Shell Scripts
    Lecture 17 The Shell and Shell Scripting In this lecture • The UNIX shell • Simple Shell Scripts • Shell variables • File System commands, IO commands, IO redirection • Command Line Arguments • Evaluating Expr in Shell • Predicates, operators for testing strings, ints and files • If-then-else in Shell • The for, while and do loop in Shell • Writing Shell scripts • Exercises In this course, we need to be familiar with the "UNIX shell". We use it, whether bash, csh, tcsh, zsh, or other variants, to start and stop processes, control the terminal, and to otherwise interact with the system. Many of you have heard of, or made use of "shell scripting", that is the process of providing instructions to shell in a simple, interpreted programming language . To see what shell we are working on, first SSH into unix.andrew.cmu.edu and type echo $SHELL ---- to see the working shell in SSH We will be writing our shell scripts for this particular shell (csh). The shell scripting language does not fit the classic definition of a useful language. It does not have many of the features such as portability, facilities for resource intensive tasks such as recursion or hashing or sorting. It does not have data structures like arrays and hash tables. It does not have facilities for direct access to hardware or good security features. But in many other ways the language of the shell is very powerful -- it has functions, conditionals, loops. It does not support strong data typing -- it is completely untyped (everything is a string). But, the real power of shell program doesn't come from the language itself, but from the diverse library that it can call upon -- any program.

Why write shell programs? • Run tasks customised for different systems. Variety of environment variables such as the operating system version and type can be detected within a script and necessary action taken to enable correct operation of a program. • Create the primary user interface for a variety of programming tasks. For example- to start up a package with a selection of options. • Write programs for controlling the routinely performed jobs run on a system. For example- to take backups when the system is idle. • Write job scripts for submission to a job-scheduler such as the sun- grid-engine. For example- to run your own programs in batch mode.
