THE 2013 INTERNATIONAL WORKSHOP ON STATISTICAL METHODOLOGY FOR HUMAN GENOMIC STUDIES UNIX cheat sheet – Sarah Medland Help on any Unix command man {command} Type man ls to read the manual for the ls command. which {command} Find out where a program is installed whatis {command} Give short description of command. List a directory ls {path} ls -l {path} Long listing, with date, size and permisions. ls -R {path} Recursive listing, with all subdirs. Change to directory cd {dirname} There must be a space between. cd ~ Go back to home directory, useful if you're lost. cd .. Go back one directory. Make a new directory mkdir {dirname} Remove a directory/file rmdir {dirname} Only works if {dirname} is empty. rm {filespec} ? and * wildcards work like DOS should. "?" is any character; "*" is any string of characters. Print working directory pwd Show where you are as full path. Copy a file or directory cp {file1} {file2} cp -r {dir1} {dir2} Recursive, copy directory and all subdirs. cat {newfile} >> {oldfile} Append newfile to end of oldfile. Move (or rename) a file mv {oldfile} {newfile} Moving a file and renaming it are the same thing. View a text file more {filename} View file one screen at a time. less {filename} Like more , with extra features. cat {filename} View file, but it scrolls. page {filename} Very handy with ncftp . nano {filename} Use text editor. head {filename} show first 10 lines tail {filename} show last 10 lines Compare two files diff {file1} {file2} Show the differences. sdiff {file1} {file2} Show files side by side. Other text commands grep '{pattern}' {file} Find regular expression in file. -
What Is UNIX? the Directory Structure Basic Commands Find
What is UNIX? UNIX is an operating system like Windows on our computers. By operating system, we mean the suite of programs which make the computer work. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops. The Directory Structure All the files are grouped together in the directory structure. The file-system is arranged in a hierarchical structure, like an inverted tree. The top of the hierarchy is traditionally called root (written as a slash / ) Basic commands When you first login, your current working directory is your home directory. In UNIX (.) means the current directory and (..) means the parent of the current directory. find command The find command is used to locate files on a Unix or Linux system. find will search any set of directories you specify for files that match the supplied search criteria. The syntax looks like this: find where-to-look criteria what-to-do All arguments to find are optional, and there are defaults for all parts. where-to-look defaults to . (that is, the current working directory), criteria defaults to none (that is, select all files), and what-to-do (known as the find action) defaults to ‑print (that is, display the names of found files to standard output). Examples: find . –name *.txt (finds all the files ending with txt in current directory and subdirectories) find . -mtime 1 (find all the files modified exact 1 day) find . -mtime -1 (find all the files modified less than 1 day) find . -mtime +1 (find all the files modified more than 1 day) find . -
Bash Scripts for Avpres Verify Manifest(1)
verify_manifest(1) Bash Scripts for AVpres verify_manifest(1) NAME verify_manifest - Verify a checksum manifest of a folder or file SYNOPSIS verify_manifest -i input_path [-m manifest_file] verify_manifest -h | -x DESCRIPTION Bash AVpres is a collection of Bash scripts for audio-visual preservation. One of these small programs is verify_manifest.Itcreates a checksum manifest of a folder or file. Bash version 3.2 is required, but we strongly advise to use the current version 5.1. OPTIONS BASIC OPTIONS -i input_path,--input=input_path path to an input folder or file -m manifest_file,--manifest=manifest_file path to the manifest file If this parameter is not passed, then the script uses for a folder: <input_path>_<algorithm>.txt and for a file: <input_path>_<extension>_<algorithm>.txt ADVA NCED OPTIONS The arguments of the advanced options can be overwritten by the user.Please remember that anystring containing spaces must be quoted, or its spaces must be escaped. --algorithm=(xxh32|xxh64|xxh128|md5|sha1|sha256|sha512|crc32) We advise to use a faster non-cryptographic hash functions, because we consider that, for archival purposes, there is no necessity to apply a more complexunkeyed cryptographic hash function. The algorithm name can be passed in upper or lower case letters. The default algorithm is xxHash 128: --algorithm=xxh128 Note that until end of 2020 the default algorithm was MD5, which has the same checksum size than the xxHash 128 algorithm. Therefore, if you verity files with an MD5 checksum, then you may pass the option --algorithm=md5 in order to speed-up the verification. Also xxHash 32 and CRC-32 have the same checksum size. -
Download Instructions—Portal
Download instructions These instructions are recommended to download big files. How to download and verify files from downloads.gvsig.org • H ow to download files • G NU/Linux Systems • MacO S X Systems • Windows Systems • H ow to validate the downloaded files How to download files The files distributed on this site can be downloaded using different access protocols, the ones currently available are FTP, HTTP and RSYNC. The base URL of the site for the different protocols is: • ftp://gvsig.org/ • http://downloads.gvsig.org/ • r sync://gvsig.org/downloads/ To download files using the first two protocols is recommended to use client programs able to resume partial downloads, as it is usual to have transfer interruptions when downloading big files like DVD images. There are multiple free (and multi platform) programs to download files using different protocols (in our case we are interested in FTP and HTTP), from them we can highlight curl (http://curl.haxx.se/) and wget (http://www.gnu.org/software/wget/) from the command line ones and Free Download Manager from the GUI ones (this one is only for Windows systems). The curl program is included in MacOS X and is available for almost all GNU/Linux distributions. It can be downloaded in source code or in binary form for different operating systems from the project web site. The wget program is also included in almost all GNU/Linux distributions and its source code or binaries of the program for different systems can be downloaded from this page. Next we will explain how to download files from the most usual operating systems using the programs referenced earlier: • G NU/Linux Systems • MacO S X Systems • Windows Systems The use of rsync (available from the URL http://samba.org/rsync/) it is left as an exercise for the reader, we will only said that it is advised to use the --partial option to avoid problems when there transfers are interrupted. -
