Linux – find / grep command without searching mounted shares

Try

find /srv/www/*/htdocs/system/application/ -name "*.php" -exec grep "debug (" {} \; -print

This should recursively search the folders under application for files with .php extension and pass them to grep.

An optimization on this would be to execute:

find /srv/www/*/htdocs/system/application/ -name "*.php" -print0 | xargs -0 grep -H "debug ("

This uses xargs to pass all the .php files output by find as arguments to a single grep command; e.g., grep "debug (" file1 file2 file3. The -print0 option of find and -0 option of xargs ensure the spaces in file and directory names are correctly handled. The -H option passed to grep ensures that the filename is printed in all situations. (By default, grep prints the filename only when multiple arguments are passed in.)

From man xargs:

-0

Input items are terminated by a null character instead of by whitespace, and the quotes and backslash are not special (every character is taken literally).  Disables the end of file string, which is treated like any other argument.  Useful when input items might contain white space, quote marks, or backslashes.  The GNU find -print0 option produces input suitable for this mode.

Use find trunk/messages/ -name "*.po" -exec basename {} .po \;

Example and explanations:

Create some test files:

$ touch test1.po  
$ touch test2.po  
$ find . -name "*.po" -print
./test1.po  
./test2.po

Ok, files get found, including path.

For each result execute basename, and strip the .po part of the name

$ find . -name "*.po" -exec basename \{} .po \;  
test1  
test2
