Read only a segment of text line

Question

I have a path only part of which actually exists. I want my script to complete the entire path (the script is for backup purposes).

for example :

/home/usr/guy/WDcloud/Linux/pi/backup/usr1
                           ^
                           the actual path up to here exists

I can't use mkdir /home/usr/guy/WDcloud/Linux/pi/backup/usr1 since only part of it exists.

I want a script to check the entire path exists, and if not, complete missing directories and then commence backup for each user.

Answer 1

If the question is only about mkdir, use mkdir -p /your/partly/existing/path. From the man page:

-p Create any missing intermediate pathname components

But what do you mean by "backup for each use"?
