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.

its useful to run dos2unix command later on them.


There is 1 alternative - vote for the best!

Terminal - Alternatives
find . -type f -exec fgrep -l $'\r' "{}" \;

Looking for carriage returns would also identify files with legacy mac line endings. To fix both types:

perl -i -pe 's/\r\n?/\n/g' $(find . -type f -exec fgrep -l $'\r' "{}" \;)
grep -UIlr "^M" *

Functions: grep

Where ^M is entered by ctrl-v-m (v then m). Especially useful on cygwin when checking into a version control system. If you're not using all cygwin tools (e.g. strawberry perl instead of cygwin perl) you'll find yourself dealing with this constantly.

-U tells grep to process the file as binary; it needs this to work

-I ignores binary files so you won't get false positives

-l only prints the filename instead of the offending lines

-r recursive

Know a better way?

If you can do better, submit your command here.

What others think

Strictly speaking you should search for "\r\n" instead, as this is the actual DOS eol sequence.
