Bash backup specified file extensions in multiple directories -


i have line here find "$directory" -name "*.sh" -print0 | xargs -0 cp -t ~/bckup backs ending in .sh. how multiple file extensions? i've tried different combinations of quotes, parentheses , $. none of them worked =\

i file extensions different folders , i'm not sure how search file name specific extension.

here whole code in case:

#!/bin/bash   collect() { find "$directory" -name "*.(sh|c)" -print0 | xargs -0 cp -t ~/bckup #xargs handles files names spaces. gives error of "cp: not overwrite just-created" if file didn't exist }  echo "starting log"  timelimit=10 echo "please enter directory collect. if no input in 10 secs, default of /home selected"  read -t $timelimit directory  if [ ! -z "$directory" ] #if directory doesn't have length of 0 echo -e "\nyou want copy $directory." #-e \n work , won't show part of string else directory=/home/ echo "time's up. backup in $directory" fi  if [ ! -d ~/bckup ] echo "directory not exist, creating now" mkdir ~/bckup fi   collect echo "finished collecting"  exit 0

one option might use builtin logical or (from find man page):

   expr1 -o expr2           or; expr2 not evaluated if expr1 true.

so in case can do:

find "$directory" -name '*.c' -o -name '*.sh'
