Assign perl output to ksh shell variable
Hello,
I am writing a ksh script on an AIX system. I need to get the date and time from a file into a variable. I found the following perl script from another post on this site and modified it slightly to output the format I need:

Code:
perl -e '@d=localtime ((stat(shift))[9]); "%02d%02d%04d_%02d%02d%02d", $d[3],$d[4]+1,$d[5]+1900,$d[2],$d[1],$d[0]' <filename>


I need to get the output of the above perl into a variable in my ksh script. Is this possible to do or would I need to write the script in perl instead?

Thanks!

Code:
var=`perl -e '@d=localtime ((stat(shift))[9]); "%02d%02d%04d_%02d%02d%02d", $d[3],$d[4]+1,$d[5]+1900,$d[2],$d[1],$d[0]' <filename>`

or
Code:
var=$(perl -e '@d=localtime ((stat(shift))[9]); "%02d%02d%04d_%02d%02d%02d", $d[3],$d[4]+1,$d[5]+1900,$d[2],$d[1],$d[0]' <filename>)

Hi Franklin52,
Thanks for the quick response. I tried both things you suggested but neither of them worked. I've noticed that code that works on unix does not necessarily work on AIX.

If I could redirect the output from the perl statement to a file then I could open the file and read the data. Do you know of any way to do that?

Thanks

You can redirect the output to a file like:
Code:
perl -e '...' filename > outfile

If the output is 1 line you can read it in a variable like:
Code:
< outfile read var
echo "$var"

otherwise you have to use a loop to read the lines:
Code:
while read var
do
  # do your stuff with $var
done < outfile
