If inside a for loop

Hey Guys,

Quick one... been researching this but to no avail.

If I have a For Loop that looks something like:

Code:

for i in $XXX; do

command

done

If I want to put an if statement in there to say, if file exists move to the next file.. how would I go about it?

I've tried something like:

Code:

for i in $XXX; do

if [ -f $i ]; then next

else

command

fi

done

However it does not like the next, I've also tried skip...

Am I close?

Hi

You could use "continue" instead of "next". Or simply use ! for "not":

Code:

for i in $XXX; do

  if [ ! -f "$i" ]; then 

    command

  fi

done

Also, if you put quotes around $i, it will handle filenames with spaces.

You could also try:

Code:

[[ -f "$i" ]] && continue
