FreeDup 1.4-2 (Default branch)
ImageFreedup finds and eliminates duplicate files by linking them, and thus reduces the amount of used disk space withinone or more file systems. By default, hardlinks are used on a single device, symbolic links when the devices differ. A set of options allows you to modify the methods of file comparison, the hash functions, the linking behavior, and the reporting style. You may use batch or interactive mode. Freedup usually only considers identical files, but when comparing audio or graphics files, you may elect to ignore the tags.License: GNU General Public License (GPL)Changes:
You now have full capabilities to determine link direction, which is particularily helpful when more then two files need to be linked. Also, the limitation that not more than 256 files may be identical no longer exists. (For efficient memory usage, four identical files are assumed and if more exist, memory allocation is doubled each time the boundary is reached.) The "-H" switch allows you to treat files that are already linked as duplicates, too. Without "-H", depending on the linking directions, the results can vary.Image

git-symbolic-ref

GIT-SYMBOLIC-REF(1)                                                 Git Manual                                                 GIT-SYMBOLIC-REF(1)

NAME

       git-symbolic-ref - Read, modify and delete symbolic refs

SYNOPSIS

       git symbolic-ref [-m <reason>] <name> <ref>
       git symbolic-ref [-q] [--short] <name>
       git symbolic-ref --delete [-q] <name>

DESCRIPTION

       Given one argument, reads which branch head the given symbolic ref refers to and outputs its path, relative to the .git/ directory.
       Typically you would give HEAD as the <name> argument to see which branch your working tree is on.

       Given two arguments, creates or updates a symbolic ref <name> to point at the given branch <ref>.

       Given --delete and an additional argument, deletes the given symbolic ref.

       A symbolic ref is a regular file that stores a string that begins with ref: refs/. For example, your .git/HEAD is a regular file whose
       contents is ref: refs/heads/master.

OPTIONS

       -d, --delete
           Delete the symbolic ref <name>.

       -q, --quiet
           Do not issue an error message if the <name> is not a symbolic ref but a detached HEAD; instead exit with non-zero status silently.

       --short
           When showing the value of <name> as a symbolic ref, try to shorten the value, e.g. from refs/heads/master to master.

       -m
           Update the reflog for <name> with <reason>. This is valid only when creating or updating a symbolic ref.

NOTES

       In the past, .git/HEAD was a symbolic link pointing at refs/heads/master. When we wanted to switch to another branch, we did ln -sf
       refs/heads/newbranch .git/HEAD, and when we wanted to find out which branch we are on, we did readlink .git/HEAD. But symbolic links are
       not entirely portable, so they are now deprecated and symbolic refs (as described above) are used by default.

       git symbolic-ref will exit with status 0 if the contents of the symbolic ref were printed correctly, with status 1 if the requested name is
       not a symbolic ref, or 128 if another error occurs.
