Week 49 - 'find' and 'xargs' (30 June 2003)
by
Adrian Mayo - Senior Editor for Mac OS X Unix
Thursday - Too Many Files?
If 'find' finds many, many files, the resulting command line formed by 'xargs' may be too long. Limit this by using option '-n' which states the maximum number of parameters that 'xargs' will pass to the command (in this example to 'grep')
% find . -iname "*.ws" | xargs -n100 grep -il warning
...causes 'xargs' to call 'grep' once it has 100 filenames. If 350 filenames were found, 'xargs' would call 'grep' four times.
