[ale] sed

[terry at bitlinx.com (Terry Bailey)]

Hi,

I want to take a text file and replace each occurrence of abc with 
xyz.  I know that this can be done with an editor like nano; however, 
I want to do this within a Perl script.   I think sed can be used to 
do this and I have known about it since my UNIX days, but have never 
used it. Can anyone tell me what the syntax would be?

Thanks,

Terry Bailey
