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.

Functions

Compare a remote file with a local file

Terminal - Compare a remote file with a local file
diff /path/to/localfile <(ssh [email protected] cat /path/to/remotefile)

Compare a remote file with a local file

Or, if you have restricted access for sftp only, I think you can still do this:

diff /path/to/localfile <(scp [email protected]:/path/to/remotefile >(cat))

Alternatives

There are 2 alternatives - vote for the best!

Terminal - Alternatives
ssh [email protected] cat /path/to/remotefile | diff /path/to/localfile -
2009-02-04 11:33:19
User: root
Functions: cat diff ssh
162

Useful for checking if there are differences between local and remote files.

vimdiff <file> scp://[<user>@]<host>/<file>
diff <(ssh [email protected] cat /path/to/remotefile) /path/to/localfile
vimdiff scp://[[email protected]]host1/<file> scp://[[email protected]]host2/<file>

A little messy, but functional. Requires vim >= 7.x.

test "$(md5sum /local/file | cut -d' ' -f1)" == "$(ssh [email protected] -- md5sum /remote/file | cut -d' ' -f1)" && echo "Match" || echo "Differ"

This method does not transfer the contents of the entire file, instead it computes a md5 sum of the file on each end so that large files can be compared without transferring them across the net.

Know a better way?
