Top Forums UNIX for Dummies Questions & Answers use of xargs and prune piping with find command. Post 302281115 by rwuerth on Wednesday 28th of January 2009 08:29:26 AM

the -prune option prevents find from walking a subdirectory underneath it's current location. Without prune, you might print a listing as follows:

file1
file2
dir1
dir1/file1
dir1/file2
file3
file4

With prune you would print a listing like this:

file1
file2
dir1
file3
file4

When the command is piped into xargs followed by another command like the 'rm' in your example xargs acts as like a loop for the input coming from the pipe and runs the command (rm -f ) for each line of input.

The directory wont be removed by rm -f but the error will be sent to /dev/null so the user wont see this. The effect is that the files will be removed but not the directories, nor the files in the directories.

NAME
opendiff -- Use FileMerge to graphically compare or merge file or directories SYNOPSIS
opendiff file1 file2 [-ancestor ancestorFile] [-merge mergeFile] opendiff dir1 dir2 [-ancestor ancestorDirectory] [-merge mergeDirectory] DESCRIPTION
opendiff is a command line utility that provides a convenient way to launch the FileMerge application from Terminal to graphically compare files or directories. If FileMerge is already running, opendiff will connect to that running instance for the new comparison. opendiff exits immediately after the comparison request has been sent to FileMerge. opendiff and FileMerge can be used to compare two files file1 and file2 or to compare two directories dir1 and dir2. If the -ancestor flag is given, FileMerge will compare the two files or directories to a common ancestor. This is useful if two people inde- pendently modify copies of a single original file or directory. FileMerge lets you merge two files or directories together to create a third file or directory. To see the contents of a merged file, drag the splitter bar at the bottom of FileMerge's file comparison window. The contents of the merged file can be directly edited within File- Merge. After editing, the merged file can be saved to the file (or into the directory) specified with the Fl merge flag. If a destination is not specified with the -merge flag, FileMerge will ask for a destination file or directory when you try to save a merged file. For further information, please consult the Help information available from the FileMerge application. FILES
