hi,
after migration perl from aix to Linux, the script does not work.
here is the code and error message:#!/usr/bin/kshexport SCRIPT=$(basename $0)export PROJECT_DIR=/usr/local/aml3/opfIN_FILE=/usr/local/aml3/opf/OCIF/cfg/eval_config.cfgcat $IN_FILE | \
perl -ne \
'
sub leave { print STDERR $ENV{SCRIPT}, ": file [", $ENV{IN_FILE}, "]: line [$lineCount]: error: [", $_[0], "]", "\n";
exit 1
} $line = $_;
$line =~ s/\n//o;
$out = ""; $lineCount++; while ($line =~ m/ (([^\$] | \$[0-9])+) | (( \$ ( ({ [_a-zA-Z][_a-zA-Z0-9]* } ) |
( [_a-zA-Z][_a-zA-Z0-9]* )
)
)+)
/xgo)
{
if ($1) { $out .= $1 }
if ($3) { open E, "eval print -n \"$3\" |" or leave "cannot eval";
read E, $e, 4096 or leave "cannot read from eval";
close E;
$out .= $e
} # the open above fails if eval returns an error
# or if eval does not output anything to stdout
} printf $out, "\n";
'--------sh: print: command not found
test_perl.ksh: file []: line [1]: error: [cannot read from eval]
the sample test file: /usr/local/aml3/opf/OCIF/cfg>cat eval_config.cfg
${PROJECT_DIR}/OCIF/cfg/catalog.cfg.templ : ${PROJECT_DIR}/OCIF/cfg/catalog.cfg
