Extracting zip from Terminal with renaming when filename exists?
You can do it with the -B switch.
-B [when compiled with UNIXBACKUP defined] save a backup copy of
each overwritten file. The backup file is gets the name of the
target file with a tilde and optionally a unique sequence number
(up to 5 digits) appended. The sequence number is applied when‐
ever another file with the original name plus tilde already
exists. When used together with the "overwrite all" option -o,
numbered backup files are never created. In this case, all
backup files are named as the original file with an appended
tilde, existing backup files are deleted without notice. This
feature works similarly to the default behavior of emacs(1) in
many locations.
Example: the old copy of ``foo'' is renamed to ``foo~''.
Warning: Users should be aware that the -B option does not pre‐
vent loss of existing data under all circumstances. For exam‐
ple, when unzip is run in overwrite-all mode, an existing
``foo~'' file is deleted before unzip attempts to rename ``foo''
to ``foo~''. When this rename attempt fails (because of a file
locks, insufficient privileges, or ...), the extraction of
``foo~'' gets cancelled, but the old backup file is already
lost. A similar scenario takes place when the sequence number
range for numbered backup files gets exhausted (99999, or 65535
for 16-bit systems). In this case, the backup file with the
maximum sequence number is deleted and replaced by the new
backup version without notice.
