checking files in current and sub directories, finding out the files containing "sampleString" and removing the containing lines from the file.

* Beware that The command will update the original file [no backup].

The command can be extended if play with 'find' command together,

e.g. it is possible to execute on certain type of files: *.xml, *.txt... (find -name "*.xml" | grep....)

if anybody knows a better solution on that, please drop a comment. thx.

sed -i.bak or sed -i.`date +%F` will make a backup

Will break on file names that contain ":" characters. Better use grep's -l flag (you also won't need uniq anymore):

grep -rl "sampleString". | xargs sed ...

If your filenames might contain spaces or other nasty characters, you need two more options:

grep -rl --null "sampleString". | xargs -0 sed ...

The perl command that scw talks about is to edit some strings in file not to delete the whole line.
