Hi Friends,

Could any body please guide me how to concatenate the value of two variable?

I have Googled for it and found lots ways but whenever I tried to concatenate I got failed.

I have tried the following lines:

JavaScript

print "Enter the name";
$baseStream = <> ;
$b = 1;
$strName = "${$baseStream}_Strm_${b}";
print $strName;

If I entered the name XYZ then expected output is : XYZ_Strm_1

But in command line I am getting output as :
XYZ
_Strm_1

I just don't understand why the output is got split in two lines.

Please help me.

Thanks in advance.

Solution 1

Your $baseStream variable is including the newline character(s). Try this:

PERL

print "Enter the name";
$baseStream = <> ;
chomp $baseStream;
$b = 1;
$strName = "${baseStream}_Strm_${b}";
print $strName;

"chomp" is a function that removes the line separator from the end of a string.
I've removed the extra $ symbol from inside "{}" too.

I have a some commands and I need to fetch their output into any veriable,
smetimes these commands give the output as a single values or sometimes in multivalue.
I wan to store them into array veriable.

Hi,
Remove the chomp and use concatenation operator(.).
