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.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Universal configuration monitoring and system of record for IT.

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.

print line and execute it in BASH

print line and execute it in BASH

Is there a way to print the line BASH is executing without copy+paste the line inside an 'echo' command?


There are 6 alternatives - vote for the best!

Terminal - Alternatives
bash -x script.sh
2010-12-15 17:01:51
Functions: bash

If script.sh contains only these two lines:

$ uname -a

$ whoami

echo <command>; !#:0-$
2010-12-15 08:28:50
User: infinull
Functions: echo

!# is the currennt line so far, by using !#:- you can go from the second arg (it's zero indexed) to the last ($)

(did I understand the problem correctly?)

set -x
$ echo "command"; `!#:0-$
2011-04-28 17:09:25
Functions: echo

since we're repeating the command there after the semicolon, we only need one backtick

Know a better way?

If you can do better, submit your command here.

What others think

set -x

Print commands and their arguments as they are executed.

At the start of a script might help you with debugging.
