Rename pictures in the command-line interface
Hello, I have one directory with some pictures that I wanna rename (I use csh, don't know if that matters). For exemple, I have: b.jpg bs.jpg bsd.jpg And I wanna change to: bsd1.jpg bsd2.jpg bsd3.jpg I really appreciate if someone can help me. :) Regards, ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I know it's quite ugly and complicatedly written, but maybe
the attached script will help. It just works, but the more
I look at it, the more I wish I hadn't written it, or just
used sh and its printf %03d mechanism. :-)
Keep in mind that the script follows the csh's sorting
order to resolve *, which usually is lexicographical
order.
For example
97.jpg
98.jpg
99.jpg
100.jpg
will, after issuing
renumber bla jpg
result in
bla_01.jpg = 100.jpg
bla_02.jpg = 97.jpg
bla_03.jpg = 98.jpg
bla_04.jpg = 99.jpg
So if you wish to do some file preparation, know that the
powerful Midnight Commander can do this for you (select and
PF6).
Here's the script now. Put it in ~/bin (and add this directory
to your $PATH) as renumber (or any name you like), give it +x
permissions and rehash to make it available to the C shell.
Then, use renumber prefix suffix. It will process ALL
files in the current directory (as I said: ugly as sin).
#!/bin/csh
if ( $1 == || $2 == ) then
echo Usage: renumber base extension
echoTarget form: base_nn[n].extension
echoFor 1 to 99 files: nn; for more than 99 files: nnn
exit 1
endif
set n = `ls -l | wc | awk '{print $1}'`
set num = `expr $n - 1`
echo ${num} files to handle.
set base = $1
set extn = $2
set n = 0
foreach f ( *.${extn} )
set n = `expr $n + 1`
if ( ${num} 99 ) then
if ( ${%n} == 1 ) then
mv ${f} ${base}_00${n}.${extn}
else if ( ${%n} == 2 ) then
mv ${f} ${base}_0${n}.${extn}
else
mv ${f} ${base}_${n}.${extn}
endif
else
if ( ${%n} == 1 ) then
mv ${f} ${base}_0${n}.${extn}
else
mv ${f} ${base}_${n}.${extn}
endif
endif
end

The sorting order is not a big problem for me, at least for now. I'm
doing the renaming in one machine with GUI then I upload the pictures to
another machine. The only reason that I need this, is because sometimes
I delete one picture on the other machine and then I have to rename
everything again.

I'm doing the renaming in one machine with GUI then I upload the pictures to another machine. The only reason that I need this, is because sometimes I delete one picture on the other machine and then I have to rename everything again. In this case, pay attention that the renumber script does not pay attention to not overwrite files. This can lead to problems when adding files. Let's say you have pic_01.jpg pic_02.jpg pic_03.jpg and add a file new.jpg, so you have new.jpg pic_01.jpg pic_02.jpg pic_03.jpg If you now run renumber pic jpg you'll have pic_01.jpg = new.jpg pic_02.jpg = pic_01.jpg pic_03.jpg = pic_02.jpg pic_04.jpg = pic_03.jpg and the source pics will be removed, so you end up with pic_04.jpg = neu.jpg A workaround is to use the MC to prefix all files with an arbitrary letter, and THEN run renumber, e. g. select all (grey *), PF6, to X* (where X is the arbitrary letter) and have Xnew.jpg Xpic_01.jpg Xpic_02.jpg Xpic_03.jpg which can be processed with renumber pic jpg now without any problems because the existing prefix isn't the same as the renumbering prefix. As you see: I have a reason to believe that I should better write a new script that takes such things into mind and maybe offer reverse renumbering, overwrite protection and a better selection which files (instead of hardcoded *) to process. So if you wish to do some file preparation, know that the powerful Midnight Commander can do this for you (select and PF6). Anyway, I gonna look at it. It's worth it. The MC is a powerful and still easy to use tool for file administration. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: Rename pictures in the command-line interface
No problem. You might also consider extending it to support '.jpeg' as
well as '.jpg', or even alter to work recursively through
sub-directories. Like I said though, it's more or less a starting
point. It will continue to extend beyond the current number each time
it's run too - so it should never over-write an existing file and
never need to be altered to support one more digit, (until system
limitations come in to play - but that's a whole other ball game in
terms of scale and probably the least of your worries at that point).
Personally I find things like this a LOT easier to do in Perl for the
power and simplicity of Perls ability to handle and manipulate
strings, (again like I'd mentioned in my original reply), I'm sure
this is do-able in a shell script too just seems simpler to
read/write/work with written in Perl to me and it just gets the job
done.

Here's something quick/dirty to work with, you can build from here,

it from withing the directory you want to work:
#!/usr/bin/perl -w

An example given a directory with files like:
blah.Jpg
bs432.jpg
bsd11.jpg
bsl.jpg
uh-oh.jpG
yourSelf.JPG
Will give you an output like:
Left off last time at 11, going to start this time at 12.
Renaming blah.Jpg to bsd12.jpg
Renaming bs432.jpg to bsd13.jpg
Renaming bsl.jpg to bsd14.jpg
Renaming uh-oh.jpG to bsd15.jpg
Renaming youSelf.JPG to bsd16.jpg

ways, and sure it's not going to be really efficient for large
volumes, but in a pinch it'll work pretty reliably.
