Give all those pictures the same name format, trailing zeros please for the right order, offset to merge different collections of pictures

Terminal - Give all those pictures the same name format, trailing zeros please for the right order, offset to merge different collections of pictures

Give all those pictures the same name format, trailing zeros please for the right order, offset to merge different collections of pictures

When you have different digital cameras, different people, friends and you want to merge all those pictures together, then you get files with same names or files with 3 and 4 digit numbers etc. The result is a mess if you copy it together into one directory.

But if you can add an offset to the picture number and set the number of leading zeros in the file name's number then you can manage.

OFFS != 0 and LZ the same as the files currently have is not supported. Or left as an exercise, hoho ;)

I love NF="${NF/#+(0)/}",it looks like a magic bash spell.

What others think

I get error messages on one group and overwriting the same file over and over again in another instance.

Error message:

bash: 02411_lifesaver_1920x1200: value too great for base (error token is "02411_lifesaver_1920x1200")

Overwriting:

`img00001.jpg' -> `000030.jpg'

mv: overwrite `000030.jpg'? y

`img00002.jpg' -> `000030.jpg'

mv: overwrite `000030.jpg'? y

`img00003.jpg' -> `000030.jpg'

mv: overwrite `000030.jpg'? ^C

Also I am not sure what the result must be.

I rename stuff with

ls *.jpg| awk '{ printf("mv '\''%s'\'' %04d-one.jpg\n", $0, ++j) }' | sh

The -one part can be different, removed or moved to the front of the numbers

Hello Houghi,

you did not understand my one liner before using it, did you ;) ?

It will work on files with names made of digits only, otherwise the offset will not work => NF=$[NF+OFFS], because it uses an addition.

If you files look have names like img00001.jpg, img00002.jpg, etc, then convert those file names to digits only like this:

for file in img*.jpg ; do mv -iv "$file" ${file#img} ; done

If you are unsure of what the command actually does put an echo before the mv -iv part like this:

for file in img*.jpg ; do echo mv -iv "$file" ${file#img} ; done

That will remove the leading "img" part of the file name.

Cheers
