need help in a script

i have written a script that will find the current seconds and convert it into the gregorian format:

Code:
#!/bin/ksh

current_time=`date +%s`
echo "$current_time"

perl -le 'print scalar localtime("$current_time");'

output i m getting
Code:
1235376784
Wed Dec 31 18:00:00 1969

my desired output:
Code:
1235376784

Hi.

There are 2 issues here.

First, the use of "-w" will help isolate problems:
Code:
#!/bin/ksh

current_time=`date +%s`
echo "$current_time"

perl -w -le 'print scalar localtime("$current_time");'

Producing:
Code:
1235386682
Name "main::current_time" used only once: possible typo at -e line 1.
Use of uninitialized value in string at -e line 1.
Argument "" isn't numeric in localtime at -e line 1.

This causes us to look at the quoting. The single quotes are protecting everything from being evaluated by the shell. One solution is to split the string we provide so that the shell can evaluate the shell variable:
Code:
#!/bin/ksh

current_time=`date +%s`
echo "$current_time"

perl -w -le 'print scalar localtime('"$current_time"');'

Producing:
Code:
1235386829

Best wishes ... cheers, drl
