It is quite easy to write your own prompt. a) The promptĮxtravagant prompts have become a badge of pride for Zshellers. When installing Zsh, you should customize two things. Head over to oh-my-zsh and follow the intructions. OK, so now you know that you need to try Zsh out. Similar to suffix aliases, if you turn on AUTO_CD, typing the name of a directory cd:s to it. alias -s pdf=xpdf Now if you just type the name of a pdf file, it will be displayed with xpdf. Zsh also has suffix aliases, which means that you can tie a file suffix, let’s say “pdf” to a command, for example xpdf. If you want to give a directory an alias, you use hash. Some examples:Īlias -g L="|less" # Write L after a command to page through the output.Īlias -g NUL="> /dev/null 2>&1" # You get the idea. Global aliasesĪliases are nice, but global aliases are words that can be used anywhere on the command line, thus you can give certain files, filters or pipes a short name. You don’t want full spelling correction on files though (deactivated per default). Great! It also has spelling correction built-in in other places, suggesting which command you might have meant, etc. ![]() ![]() When I try it will first try to complete on the exact match and then use a case insensitive match. Zsh does not care if I write a filename in lowercase or mixed or whatever. There are examples of using modules in the Zsh-lovers man page and full documentation in the Zsh Modules Documentation. For example expressing date constraints in a natural format. They can make the filters above even more interesting. Sort of like importing a library when you code. Loadable modules are modules that give your shell additional functionality. Skim through them all, when you have decided to give Zsh a try. These examples happily borrowed from Zzappers Best of ZSH Tips, Z shell made easy and Zsh-lovers man page. Ls DATA_(#c4,7).csv # List DATA_nnnn.csv to DATA_nnnnnnn.csv Ls -l */**(Lk+100) # List all files larger than 100kb in this tree Ls *~*.*(.) # List all files that does not have a dot in the filename Ls **/*(.x) # List all executable files in this tree Rm -i *(.L0) # Remove zero length files, prompt for each fileĮmacs **/main.py # Edit main.py, wherever it is in this directory tree. Ls -ld *(/om) # Show three newest directories. You can sort and filter by exclusion or inclusion on name, size, permission, owner, creation time. Globbing means command line parameter expansion. Using when writing commands is a bit like static type checking, since if you don’t get a completion you are probably writing your argument type in the wrong place.įor common use cases it is easy to write tab completion specifications for your own scripts. It knows which commands git takes, which hosts are in my hosts file for ssh, which users my system have when I write chmod, available packages to apt-get, etc. It has knowledge about an impressive number of tools and scripts. ![]() Context based tab completionįile based tab completion is great and all, but zsh has tab completion for everything. Some of these things can be enabled in Bash, but AFAIK it is not implemented quite as well. Though I have used it for 10+ years, I am far from a Bash specialist.
