concatenation in perl

satyarox has asked for the wisdom of the Perl Monks concerning the following question:

Hai all,
I am new to PERL.I have a problem in concatenation of two strings in a program.
The problem is as follows
I have a value $OID = 1.2.3.6.9.5.6.8
I have another value = 5
now i want to concatenate these two values so the output is like this 1.2.3.6.9.5.6.8.5
i already used the "." for concatenation .But while printing that value it is giving the output 1.2.3.6.9.5.6.8 in one line and .5 in other line
But i want the entire output(i.e.. 1.2.3.6.9.5.6.8.5) in one variable.could anybody please solve my problem

Thanks
Satya

It seems that `$OID` contains a trailing newline, so you have to remove that before concatenating the strings: `chomp $OID; my $new_OID = $OID . '.5'; print $new_OID, "\n";` [download]	[reply] [d/l] [select]

satyarox, I notice this is your first post, welcome to the Monastery. You should read the PerlMonks FAQ and How do I post a question effectively? if you have not already done so, since you have posted this question in the wrong section of this forum. You should take a look at quotes in Perl from the Strings subsection of the tutorials section of this site. Since you say you are new to Perl, you may want to have a look at some of the Getting Started with Perl tutorials also. Hope this helps Martin	[reply]

Are you sure you did `my $OID = "1.2.3.6.9.5.6.8"` and not `my $OID = "1.2.3.6.9.5.6.8\n"`? If you did `my $OID = <SOME_HANDLE>;`, you did the latter. To remove the trailing newline, use `chomp`: `chomp( my $OID = <SOME_HANDLE> );`	[reply] [d/l] [select]
