What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Returns the absolute path to a command, using which if needed

Terminal - Returns the absolute path to a command, using which if needed
which any_path/a_command.sh | sed "s|^./|$(pwd)|"

Returns the absolute path to a command, using which if needed

This works in multiple unixes, not only linux, for different paths.

On solaris, if you do not have which, you can use:

ksh whence -p anypath/a_command.sh | sed "s|^./|$(pwd)|" ksh whence -p


There are 14 alternatives - vote for the best!

Terminal - Alternatives
get_absolute_path() { echo $1 | sed "s|^\([^/].*/.*\)|$(pwd)/\1|;s|^\([^/]*\)$|$(which -- $1)|;s|^$|$1|"; }

User: keymon
Functions: echo sed

It will return the absolute location of the called a script. If is in $PATH, it will search it using which.

You can combine this function with this other one: http://www.commandlinefu.com/commands/view/9252/readlink-equivalent-using-shell-commands-and-following-all-links, to get a way to know where is the real location of a called script:

# Returns the realpath of a called command. whereis_realpath() { local SCRIPT_PATH=$(whereis $1); myreadlink ${SCRIPT_PATH} | sed "s|^\([^/].*\)\$|$(dirname ${SCRIPT_PATH})/\1|"; }

Know a better way?

If you can do better, submit your command here.

What others think

dirname `which a_command.sh`

On solaris:

$ dirname .

And if you write a relative path, AFAIK in linux it does not work:

$ dirname `which ./bin/a_command.sh` ./bin/a_command.sh
