Foo bar in reverse for 10 times _ Perl program

[R A J Rajkishore]

I have to open a text file in which "foo bar" is written in 10 times.

Example:

foo bar

foo bar

foo bar

.

.

.

.

.foo bar

I have to get the output in perl window as 

 bar foo

 bar foo

 bar foo

 bar foo

 bar foo

 .

 .

 .

 ..

 bar foo

10times as reversed of "foo bar" 

Please help in perl

A perl version to switch the two columns in the file could look like this: 

perl -ane 'print $F[1], " ", $F[0], "\n"' foobar

see 'man perlrun' for documentation of command line perl

However, for these simple tasks, awk is still better because easier and less error prone:

awk '{print $2, $1}' foobar

Yes you can. But the other solutions are easier, unless you are thinking that will become a bigger, and more complex, script.
