on the other hand i have a text file with 2 columns asa follows:

36771 yellow
33456 red
abcde black
22341 pink

what i need :

i need to rename each file with color correspondance from text file.

so file named 1-33456.jpg becomes red.jpg


i've already tryed working with text arrays but no success...
any help will be much apreciated.

Try this (presumes that the *.jpg files are in the current directory, and that the colours are stored in a file called colours):

ls *.jpg | awk '
        BEGIN {
                while (getline < "colours") { colour[$1]=$2 }
                close("colours")
                FS="[-.]"
        }
        {
                newname=$0
                sub("1-"$2,colour[$2],newname)
                print "mv",$0,newname
        }
' | sh -x

Hi

Then
[ol]
[li]put the script into a file and pass its name to [tt]awk95[/tt][/li]
[li]replace [tt]mv[/tt] with [tt]ren[/tt][/li]
[li]redirect the script's output into a file with .bat extension[/li]
[li]run the .bat file[/li]
[/ol]
Or
[ol]
[li]Install CygWin.[/li]
