I am learning shell Scripting on my own, and I was investigation how to do the If, and I didn’t understand an example that had:
if [ -f ./$NAME.tar ]; then
//do something
else
//something else
Now I did some experimenting, and I gave NAME the name of a file I had on my directory. When I executed without the -f, it was entering in the else condition, but with -f it enters the //do something condition So I presume -f is for file. Is this correct? I just couldn’t find information to confirm this.
From
bash
manual:So yes,
-f
means file (./$NAME.tar
in your case) exists and is a regular file (not a device file or a directory for example).
