[SOLVED] mkdir linux alternative that can make directories the paths specified in a file done at once

Is there utility as mkdir linux alternative that can make directories the paths specified in a file done at once in a call, so that far faster, simpler, more efficient?
as mkdir can do it by for loop

Code:

(while read -r s;do
 mkdir -p $s
done ) <Paths

let that util be illustrated as

Code:

mdir -f Paths

as the file contains more 500 lines has a clear difference ?

If it is an actual problem (which I doubt), then try something like this:

Code:

cat Paths | xargs mkdir -p --

And why do you care given the hardware we all have available these days ?. What's the real cost of another shell instance ?.

In this case most probably the cost of the additional shell is negligible. The real problem is the bad habit. In general would be nice to get into the way of doing "best practices". Especially when it is not that difficult.

For example, tar(1) is known to be able to create multiple directories. Though it requires a prepared data-file.

Right, `cat` can be left out:

Code:

xargs <Paths mkdir -p --

@NevemTeve. You're brilliant !!!

the proof of your generous work

$ time (while read -r s;do mkdir -p l$s ;done) <m

real 0m1.403s
user 0m0.291s
sys 0m1.198s

$ time xargs <m mkdir -p --

real 0m0.052s
user 0m0.007s
sys 0m0.045s

Just even 477 lines in m

much low than the actual demand at least 670 lines
