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.

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 :)

While posting, I saw this http://www.commandlinefu.com/commands/view/1041/display-contents-of-a-file-wo-any-comments-or-blank-lines

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

or

egrep -v -f some_file /your/file #where some_file contains what you want to exclude, example a really inserted TAB
egrep -v "^$|^#" file
egrep -v "^[[:blank:]]*($|#|//|/\*| \*|\*/)" somefile
sed -e 's/#.*//;/^\s*$/d'
grep -v ^# /etc/somefile.conf | grep .

grep ^[^#] file

Shorter than this, I don't think so.

grep ^[^#/^$] file

To include "$" too
