fn0
Rename files to [1, N] and save the filenames to file 0.
- resolve rename conflicts with minimal cost
- safe to use
- gzip, gpg supported
Usage
Usage: fn0 {-c|-x|-l} [-f RECORD_FILE] [-zp] [-r RECIPIENT] [-FR] [DIR]...
Rename files to [1, N] and save the filenames to file 0.
Mode:
-c create record file to storage filenames
-x extract filenames in record file and remove it
-l watch record file
Options:
-f set the record file. will not remove that file. - for stdin/stdout
-z enable gzip support, ignored when using gpg to create record file
-p enable gpg decryption
-r enable gpg encryption and set recipient
-F force
with -c: works even if the record file exists, just rename it as usual
with -x: works even if not all the files exist
-R recursive

Example
- storage filenames in plain text file "0", recursive
$ ls && ls d
a b c d
da
$ fn0 -cR
$ ls && ls 4
0 1 2 3 4
0 1
$ cat 0 # or: fn0 -l
a
b
c
d
$ cat 4/0
da
$ fn0 -xR
$ ls && ls d
a b c d
da- fn0 will prevent create record file again, this will be useful when use recursive. You can disable this feature with -F
$ ls && ls d
a b c d
da
$ fn0 -c d
$ ls && ls d
a b c d
0 1
$ fn0 -cR
fn0: record file already exists: "0" at /tmp/test/4
