Using the IF statement

[roger55]

I need to select a range of files in an If statement.

The current code does this:
for x in `cat $HOME2/tmp/SFA_rpt7.ctl`
do
if [ -s $x]
then

I want to only select files in a range like so:

if ( $x >= A600.prn and $x <= A699.prn )
or ( $x >= A720.prn and $x <= A720.prn)
then

I also need to do the reverse logic like this by
selecting files that are NOT in these ranges.

If all files have the same name format why don't you just do what you want:

   for x in `cat $HOME2/tmp/SFA_rpt7.ctl`
   do
     if [[ &quot;$x&quot; < &quot;A600.prn&quot; ]]
     then
        # do whatever 
     elif [[ &quot;$x&quot; >= A600.prn && &quot;$x&quot; <= &quot;A699.prn&quot; ]]
     then
        # do something else
     elif [[ &quot;$x&quot; >= &quot;A720.prn&quot; && &quot;$x&quot; <= &quot;A720.prn&quot; ]]
        # do more stuff
     else
        # whaterever to be done
     fi
   done

You can also consider the case statement, something like this:

case $x in
A6??.prn|A720.prn)
  What do do here
  ;;
AnotherPattern)
  Another stuff
  ;;
*)
  Otherwise stuff
  ;;

I tried this command but get a syntax error:

if [ ! \( -s $x -ge A600.prn -a -s $x -le A699.prn \) -a ! \( -s $x -ge A800.prn -a -s $x -le A899.prn \) ]
then
