Hi people,
I need to match string against regular expressions that are only
known at run-time. I'm having problems doing it so I made a small test
script like the following :
#!/net/tcmvega35/data1/automation/perl/bin/perl -w
use strict;
die "test.pl [string] [regex]" unless $#ARGV == 1;
if ($ARGV[0] =~ $ARGV[1])
{
print "$ARGV[0] matches $ARGV[1]\n";
}
else
{
print "$ARGV[0] does not match $ARGV[1]\n";
}
On the command lines, the following happend
allo al => match
allo /al/ => no match (should match, no ?)
allo lo$ => match
allo ^al => match
allo ^ao$ => no match (should match, no ?)
Questions :
- Why don't I need the regular expression delimiters (/), is it
implicit when using
variables ?
- If I don't add them (/), will it still work for all cases ?
- Why doesn't the last case work ?
Thanks !
