Aia, your explanation is correct, the {action} is performed but without printing!
Rather than the lazy
I suggest
that shows that the action needs an explicit print (the print is short for print $0). Also it does not assign values to the x array (saves some memory); the lookup ($0 in x) only needs the keys not the values.

Must be a bug or something. Whether I escape them or not, it will not work. No matter what I set the minimum and maximum to nothing gets caught. For instance:
find / -regex "/.{0, 50}.*" -maxdepth 1 or find / -regex "/.\{0, 50\}.*" -maxdepth 1 should pretty much catch everything residing within... (4 Replies)

I'm having trouble understanding the exclude option in tar. From some web sites, it seems one is able to exclude several strings by enclosing them in curly brackets. However it seems to be "random" what gets excluded when using the curlies.

opendiff
opendiff(1) BSD General Commands Manual opendiff(1)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.
