Hi, I got a perl script that begins like this. ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- - #!/usr/bin/sh -- # -*- perl -*- eval 'ORACLE_HOME=/opt/oracle; export ORACLE_HOME;LD_LIBRARY_PATH=/opt/ oracle/lib; export LD_LIBRARY_PATH; exec /bin/perl $0 ${1+"$@"} ;' if 0; #Pel statements start from here ---------------------------------------------------------------------------- ---------------------------------------------------------------------------- My guess is it's setting some shell variables (environment), and then launching the perl interperter so that the rest of the script is treated as a perl script. But, I would really appreicate it, if somebody can explain me what's happening here exactly. Thanks! ******************************************************************** Hi, It tells which program to use for execution of the script on LINUX & UNIX. So in your case it would be first using the shell. If you use Perl on windows 'Shebang' line will be treated like a perl comment i.e. after '#' everything following in that line will be treated as comment. Thanks & Regards Sanket Vaidya *************************************************************************** Forgot to add group in the loop.
