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.

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.

change the all files which contains xxxxx to yyyyyy

This script first find all files which contains word xxxxx recursively. Then replace the word xxxxx to yyyyy of the files.

Use case:

- Web site domain change

- Function name change of the program


There are 2 alternatives - vote for the best!

What others think

The perl command is wrong, shoud be perl -i -pe "s/xxxx/yyyy/g"

Also, this breaks on files with spaces.

echo "This contains xxxxx, see?" > "filename" echo "This also contains xxxxx, see?" > "filename two" cat "filename"

This contains xxxxx, see?

cat "filename two"

This also contains xxxxx, see?

grep -r -l xxxxx . | xargs perl -pi "s/xxxxx/yyyyy/g"

Can't open perl script "s/xxxxx/yyyyy/g": No such file or directory

grep -r -l xxxxx . | xargs perl -i -pe "s/xxxxx/yyyyy/g"

Can't open two: No such file or directory, line 1.

cat "filename"

This contains yyyyy, see?

cat "filename two"

This also contains xxxxx, see?

This works better:

grep -r -l xxxxx . | while read f ; do perl -i -pe 's/xxxxx/yyyyy/g' "$f" ; done cat "filename two"

This also contains yyyyy, see?

Thanks. I fixed the typo.

Here's a find/sed equivalent:

find . -exec sed -ir 's/xxxxx/yyyyy/g' {} \;
