one line awk 2

[mdarsot]

I have 48 files that i want to rename.

current filenames are
12345.zip
12346.zip
etc

New name should be
acx001.zip
acx002.zip
etc

How can i write one line awk statement to do incrementation of numbers. I have following code so far.

ls * | awk '{print "mv "$1," acx001.dat"}' > tt.sh
i am doing above and then edition tt.sh to manually increment acx001 to acx048. Is there a way to automate this.

please help

Thanks

Hi

ls * | awk '{printf "mv %s acx%03d.dat\n",$0,++i}' > tt.sh

Note, that I used $0 instead of $1, thinking to possible spaces in the filenames.

That worked great. If you dont mind can you please explain the one liner.

Hi

[tt]printf[/tt] - like the [tt]print[/tt] function, but with formating ( like the C [tt]printf[/tt] function, man 3 printf )
[tt] %s [/tt] - to be replaced with the next argument treated as string
[tt] %03d[/tt] - to be replaced with the next argument treated as decimal number, padded to length 3 with character "0"
[tt]++i [/tt] - preincrement the value of variable i and return the value

Hope This Helps, PH.

Hi

Nice observation, PHV. I think I should rise my caffeine dose.
