Question

Begin by developing a shell script that will search for files within a directory whose name contains a space. Your script should replace all spaces in a filename with an underscore.

Here is some pseudocode to help you solve this:

loop through all the files in the directory
grep for space in the filename
capture results of grep operation ($?)
Do an if test to see if it did have a space
If it did, echo the filname out and use sed to replace spaces with underscores.
Use mv command to rename file
Maybe echo out a nice message to the user
End if, end loop

Above dir "x x" containing file "u u"

 

find ./"x x" -type f -print > a

 

sed s/' '/'a'/g a > b

cat b

./xax/uau

 

in general in your home dir

 

du > a

 

grep ' ' a > b

 

cut -f2 b > c

 

sed s/' '/"' '"/g c > d

 

sed s/^/'find '/g d > e

 

sed s/$/' -type f -print '/g e > f

 

chmod u+x f

 

./f > g

 

sed s/' '/'a'/g g > h

cat h

I have a Linux Essentials certification, but I'd rather you read the Linux Journal article at:

You have identified one of the big differences between Windows and Linux.  There are many more, so get ready.
