Help with if..then..else statement
When I run the script below I get a message stating that Thu=Mon is not found. Even when I change my if statement to if $day=Thu, I get a message stating Thu=Thu is not found. How can I fix this problem?
#!/usr/bin/ksh
d=`date +%a`
if $day=Mon
then
echo Today is Monday
else
echo "$d"
fi

time::gmtime5.18
Time::gmtime(3pm) Perl Programmers Reference Guide Time::gmtime(3pm)
NAME
Time::gmtime - by-name interface to Perl's built-in gmtime() function
SYNOPSIS
use Time::gmtime;
$gm = gmtime();
printf "The day in Greenwich is %s
",
(qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $gm->wday() ];
use Time::gmtime qw(:FIELDS);
gmtime();
printf "The day in Greenwich is %s
",
(qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $tm_wday ];
$now = gmctime();
use Time::gmtime;
use File::stat;
$date_string = gmctime(stat($file)->mtime);
DESCRIPTION
This module's default exports override the core gmtime() function, replacing it with a version that returns "Time::tm" objects. This
object has methods that return the similarly named structure field name from the C's tm structure from time.h; namely sec, min, hour, mday,
mon, year, wday, yday, and isdst.
You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that
this still overrides your core functions.) Access these fields as variables named with a preceding "tm_" in front their method names.
Thus, "$tm_obj->mday()" corresponds to $tm_mday if you import the fields.
The gmctime() function provides a way of getting at the scalar sense of the original CORE::gmtime() function.
To access this functionality without the core overrides, pass the "use" an empty import list, and then access function functions with their
full qualified names. On the other hand, the built-ins are still available via the "CORE::" pseudo-package.
NOTE
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this.
