9. Shell Programming and Scripting
Hi guys,
I feel a bit comfortable now doing bash scripting but I am worried that the way I do it is not optimized and I can do much better as to how I code.
e.g.
I have a whole line in a file from which I want to extract some values.
Right now what I am doing is :

posix::strptime
POSIX::strptime(3pm) User Contributed Perl Documentation POSIX::strptime(3pm) NAME
POSIX::strptime - Perl extension to the POSIX date parsing strptime(3) function SYNOPSIS
($sec, $min, $hour, $mday, $mon, $year, $wday, $yday) = POSIX::strptime("string", "Format"); DESCRIPTION
Perl interface to strptime(3) FUNCTIONS
strptime ($sec, $min, $hour, $mday, $mon, $year, $wday, $yday) = POSIX::strptime(string, format); The result for any value not extracted is not defined. Some platforms may reliably return "undef", but this is dependent on the strptime(3) function in the underlying C library. For example, only the following fields may be relied upon: my ($min, $hour) = ( POSIX::strptime( "01:23", '%H:%M' ) )[1,2]; my ($mday, $mon, $year) = ( POSIX::strptime( "2010/07/16", '%Y/%m/%d' ) )[3,4,5]; Furthermore, not all platforms will set the $wday and $yday elements. If these values are required, use "mktime" and "gmtime": use POSIX qw( mktime ); use POSIX::strptime qw( strptime ); my ($mday, $mon, $year) = ( POSIX::strptime( "2010/07/16", '%Y/%m/%d' ) )[3,4,5]; my $wday = ( gmtime mktime 0, 0, 0, $mday, $mon, $year )[6]; SEE ALSO
