Now, I know I've asked a similar questions, but I thought that I'd ask
again with what may be a clearer request :)))))
For example:
I have a collection of images labelled -
a_0001.jpeg through to A0999.jpeg
b_0001.jpeg through to A0999.jpeg
c_0001.jpeg through to A0999.jpeg
d_0001.jpeg through to A0999.jpeg
I want to merge them as follows:
montage -geometry +4+4 a_0001.jpeg b_0001.jpeg c_0001.jpeg d_0001.jpeg
montage00001.jpeg
the output file is montage<number>.jpeg and needs to be a sequentially
increasing number.
Is there a command that will allow me to do this automatically without
having to individually enter each file name and output name?
I realise this is a little weird and no doubt unusual, but, as usual,
any assistance or direction would be most appreciated.
Not weird at all. Well organised file systems often use sequential
or semi-sequential numbering to keep things logical and consistent.
(Who said consistency is the last refuge of the unimaginative?)
The GNU seq command is useful for sequential numbering.
$ seq 1 5
1
2
3
4
5
As well, you can use printf to format the numbers as you wish, e.g.
$ for i in `seq 1 5`; do echo `printf a_%04d.jpeg $i`; done
a_0001.jpeg
a_0002.jpeg
a_0003.jpeg
a_0004.jpeg
a_0005.jpeg
Putting it all together:
$ for i in `seq 1 5`; do j=`printf %04d $i`; echo montage -geometry +4+4 a_$j.jpeg b_$j.jpeg c_$j.jpeg d_$j.jpeg
montage$j.jpeg; done
montage -geometry +4+4 a_0001.jpeg b_0001.jpeg c_0001.jpeg d_0001.jpeg
montage0001.jpeg
montage -geometry +4+4 a_0002.jpeg b_0002.jpeg c_0002.jpeg d_0002.jpeg
montage0002.jpeg
montage -geometry +4+4 a_0003.jpeg b_0003.jpeg c_0003.jpeg d_0003.jpeg
montage0003.jpeg
montage -geometry +4+4 a_0004.jpeg b_0004.jpeg c_0004.jpeg d_0004.jpeg
montage0004.jpeg
montage -geometry +4+4 a_0005.jpeg b_0005.jpeg c_0005.jpeg d_0005.jpeg
montage0005.jpeg
Get rid of the "echo" command, change 5 to 999 and Bob's your aunty.
cheers
