Created page with "==grep with find== Given the common <code>grep</code> command <syntaxhighlight lang=bash> grep -R 'pattern' * </syntaxhighlight> a corresponding <code>find -exec</code> com..."

New page

==grep with find==

Given the common <code>grep</code> command

<syntaxhighlight lang=bash>
grep -R 'pattern' *
</syntaxhighlight>

a corresponding <code>find -exec</code> command should add <code>-H</code> to include the filename prefix in the results. (This is needed because the filenames are given one at a time.)

<syntaxhighlight lang=bash>
find … -exec grep -H -R 'pattern' {} \;
</syntaxhighlight>
