for f in *.mp4,*.mov,*.ogv ?? how can you use multiple filetypes? shell script

danpaluska · 02-10-2010, 06:39 PM

in code such as

Code:

for f in *.mp4;do

# perform operations on f here
echo $f

done

is it possible to specify multiple filetypes?
i have used *.m* for multiple movie types on my mac, .mov,m4v,mp4 but it doesn't cover ogv.
i'd like to get ogv and mp4 both on my linux box. is there syntax for this?

thanks,
dan

Code:

for f in ./*.mp3 ./*.ogg ./*.mkv ; do
   echo "$f"
done

How about

Code:

for f in *.m* *.ogv; do
    echo "$f"
done

tuxdev was faster.
However you might want to add an if in your loop:

Code:

for s in ./*.m* ./*.ogv; do
 if [[ '*' != "${s:2:1}" ]]; then
  echo "$s"
 fi
done

Without 'if' you will get output like

Code:

*.ogv

if there are no files with 'ogv' suffix. The if-condition prevents that.

It should be 'do' and not 'then'.

no need. set nullglob before commencing the for loop

Code:

shopt -s nullglob

you can also do this

Code:

for f in *.{mov,m4v,mp4}
do
  #process $f
  echo $f
done
