Need direction inserting variables in a line

[lenjturnbull]

I have inserted text in a line with no problem
but i am lost when trying to put a variable example (A$) in a line of a file
example
perl -i.tmp -p -e 'print "$A$\n" if /THR/' $file.tmp

the line show up blank but inserted before THR
the variable is loaded right before this line of code.

any help
Thanks,


Len

Hauter
I have tried your code exactly with the apostrophe after the /THR/ and without and I get no results
Is there any other syntax that I need to use ???

example
$ perl -i.tmp -p -e print '$var4\n' if /THR/' $file.tmp

I even tried different entries another example with results

$ perl -i.tmp -p -e print '$var4\n' if /THR/ $file.tmp
Can't open $var4\n: A file or directory in the path name does not exist.
Can't open if: A file or directory in the path name does not exist.
Can't open /THR/: A file or directory in the path name does not exist.


I am on a RS6000 Aix 4.3 system if that is of any use ??

Thanks for the response I appreciate it.

[tt]perl -i.tmp -p -e 'print "$A$\n" if /THR/' $file.tmp[/tt]

That's the correct way to do it, but the variable [tt]$A[/tt] won't contain any value, so it will just end up printing a blank line. In fact, the [tt]$\[/tt] will likely get replaced and you'll end up with an "n" before the line you want.

What, exactly, do you want printed before each matching line?
