What does at the end of a linux command mean

0 votes

I am a system administrator and I have been asked to run a linux script to clean the system.

The command is this:

perl script.pl > output.log &

so this command is ending with a & sign, is there any special significance of it?

I have basic knowledge of shell but I have never seen this before.
