what is "uncomment" means in linux?
 

sorry, my question is a bit stupid. Im realy new to linux that Idont know what "uncomment" means to linux. thank you.

When something is commented within a language, it is not read by whatever is interpreting/compiling it. It's used to inform people of changes/messages or, like in your case, to surpress options from being read.

Assuming it's a shell script, the comments are preceeded with a #.

So if it's saying uncomment foo, you are looking to remove the # from a line reading

# foo

classic computer jargon....In this case, the verb "to uncomment" is not in the dictionary. Another abuse of the Queen's english is the action "to comment out"--turning a normally intransitive verb into a transitive one.

My favorite is "disambiguate" (also a verb). This one IS in the dictionary

thank you guys!
