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.

-n switch keeps empty columns

If your distribution does not ship with a recent column version that supports -n you can use this alternative:

perl -pe 's/(^|;);/$1 ;/g' file.csv | column -ts\; | less -S

Change the delimiter to your liking.

cat file.csv | perl -pe 'if($. == 1) {@h = split(/;/); $i = 1 ; map { $_ = $i; $i++ } @h; print join(" ;", @h) , "\n"} ; s/(^|;);/$1 ;/g' | column -ts\; | less -S

This version now adds a header with consecutive numbering.

Useless cat.

column -ts: /etc/passwd

wow - very useful - never knew that.

For csv files with semicolons use an escape of course: column -ts\; file.csv

agree cat can be made redundant
