In Zsh (and other shells), aliases may be the most important feature for increased productivity.
A simple rule is this: the more often you run a command, the shorter it should be. I’ve written about this before, in Efficient Way to Improve Console Productivity.
I have a number of one-character aliases:
I’ll write later about those nifty uppercase ones (and yes, there is the alias “a” for “alias”, but for now, I’ll just show them with examples:
alias G -g '^.='
That was the command that I ran to generate the list above. It expands to “alias | glark -g ‘^.='”.
find src -type d S
That finds all directories and pipes them to
There are three “families” of commands that I run the most often:
- diff – diff files
- eye – look at/in files on the command line
- find – list all files/directories matching a pattern
- open – open files in editor, browser
- search – look in files
So I have been writing one-character scripts/functions (in Bash) for each of the above, where the script understands context as well as the targets.
For example, “
s pluralize” run from a directory that contains a “Rakefile” will expand to search (using glark) only for Ruby files.
e program.tar.gz” is the equivalent of “
tar ztvf program.tar.gz“, and “
e program.zip” lists the zip file, with entries sorted by name.
d dir1 dir2” runs a recursive diff on the directories, and “
d path/to/file ../dir2” will diff “path/to/file” against “../dir2/path/to/file”, if the latter file exists. I do this to avoid the tedious repetition of comparing one code base to another (such as two branches, when merging them): “
diff path/to/file1 ../dir2/path/to/file1“, “
diff path/to/file2 ../dir2/path/to/file2“, etc.
Although this project is in its early stage, and the output is still rough (i.e., containing debugging output), it already has been quite useful, so I thought I would share.
The project is at Github here.
