I currently SCP the files over to the first four servers and when that transfer is complete SCP to the last 3 servers. Would using BitTorrent be faster to distribute the files to all 7 at once? The connection internally is already fast and...

Hi all, Can someone help explain the following: If I type: a=`ls -l` Then the output of the ls command is saved in the variable a but if I try: a=`sh ./somefile` The result is outputed to the shell (stdout) rather than the variable a What I expected was the result operation of the shell trying to execute a scrip 'somefile' to b...
I am writing a shell (bash) script and I'm trying to figure out an easy way to accomplish a simple task. I have some string in a variable. I don't know if this is relevant, but it can contain spaces, newlines, because actually this string is the content of a whole text file. I want to replace the last occurence of a certain substring w...

I am looking for a POSIX solution without lsof, perha...

I can't help but wonder, "how...
