IT tricks
Various tips how to increase your productivity (esp. in Linux).
Editors
Who uses which editor and is willing to provide a mini-training for new users (show config, favorite macros, highlighters etc.).
Feel free to add your name and editor.
- vim: Ondřej Bojar, Ruda Rosa, …
- emacs: ?
- atom: Martin Popel
Bash
- Use Bash auto-completion (
source /etc/bash_completion
). Some tools have plugins, e.g. many Perl tools. export HISTCONTROL=ignoreboth
results in bash history ignoring duplicate entries and entries starting with a space.
Git
- bash-git-prompt shows e.g. the current branch and status. Martin Popel prefers to configure it (in bashrc) with
export GIT_PS1_SHOWDIRTYSTATE=1 export GIT_PS1_SHOWSTASHSTATE=1 export PS1='[\t]\[\033[2;31m\]\h:\W\[\033[01;95m\]$(__git_ps1 "(%s)")\[\033[2;31m\]>\[\033[0m\] '
- tig text-mode gitk but better
- learn GitHub keyboard shortcuts, esp. “y” for permalink to a given line (line range) in source codes
Other
- When using Perl at ÚFAL, we recommend using Perlbrew with shared perl interpreters (different versions) and shared Perl modules (which otherwise take several hours to install and 6GB).
- See Python for using Python at ÚFAL.
- See remote access, esp. for byobu and mosh.
- You should not turn off Linux workstations at ÚFAL, unless really needed (or agreed with it@ufal). In that case, try the standard ways, and if they do not work, try Ctrl+Alt+SysRq+[R,E,I,S,U,B] rather than plug out power cable. Mnemonics: “Reboot Even If System Utterly Broken”, see http://en.wikipedia.org/wiki/Magic_SysRq_key#Uses
- Ondřej Bojar has implemented many Text utils, which he likes to use in his scripts and advises his students to do so as well.
