HOWTO convert a group of files in a directory to a set of sequential numbers?

lleb · 12-24-2009, 04:48 PM

example:

file_what_ever_name_here.extension
file_what_ever_again_next.extension

to 00001.extension and 00002.extension?

thanks. oh and FYI my scripting sucks. i can hardly do a simple hello bash#!

I assume by "convert" you mean rename.

Here is a for loop to help you get started.

Code:

N=1
for i in *
do
   echo $i
   echo $i |sed "s/.*\./000$N./"
   let N=N+1
   read
done

Keep in mind that this will not pad with leading zero's. Nor does it actually rename the files.
And the "read" is just a pause to help you see what it's doing.
Also; this assumes:
a) That every file in the directory will actually have an extension; and only one extension.
b) That you want the files numbered in the same order that they appear in a directory listing.

Code:

i=1
for file in file_what_ever_name_*
do 
  ext=${file##*.}
  echo mv "$file" $(printf "%05d.%s\n" $i $ext)
  ((i++))
done

Well this one displayed what the file name would look like, but failed to change the file names. first time i just hit enter, second time i hit y. That gave me the command not found bash error.

i must of goofed when i did this one. i got an error in line 5 stating no such number. the only thing i didnt do when i copied over was the "file_what_ever_name_* i just put * as i was not sure what to put here for the directory or the file name.
