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/
You can sign-in using OpenID credentials, or register a traditional username and password.
First-time OpenID users will be automatically assigned a username which can be changed after signing in.
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.
Use your favourite RSS aggregator to stay in touch with the latest commands. There are feeds mirroring the 3 Twitter streams as well as for virtually every other subset (users, tags, functions,…):
Subscribe to the feed for:
Strips comments from at least bash and php scripts. Normal # and // as well as php block comments
removes all of the:
lines beginning with #
lines beginning with //
lines beginning with /*
lines beginning with a space and then *
lines beginning with */
It also deletes the lines if there's whitespace before any of the above.
Add an alias to use in .bashrc like this:
alias stripcomments="sed -e '/^[[:blank:]]*#/d; s/[[:blank:]][[:blank:]]*#.*//' -e '/^$/d' -e '/^\/\/.*/d' -e '/^\/\*/d;/^ \* /d;/^ \*\//d'"
There are 3 alternatives - vote for the best!
Shows a file without comments (at least those starting by #)
- removes empty lines
- removes lines starting by # or "some spaces/tabs then #'"
Useful when you want to quickly see what you have to customize on a freshly installed application without reading the comments that sometimes are a full 1000 lines documentation :)
But it's dirty and incomplete, to my mind
My original goal was to remove lines like "\t*#" but I can't figure out how to do a egrep '\t' on a command-line. Two workarounds if needed:
egrep -v 'press control + V then TAB then #' /your/file
egrep -v -f some_file /your/file #where some_file contains what you want to exclude, example a really inserted TAB
easier to remember
If you can do better, submit your command here.
