YASQ Yet Another Simple Question regarding scripting
 

my pwd contains files and directories named nick and emptydr

returns the name of the directories in my pwd.

let's say I save the result of the above command into a file named listing.

then the file listing will contain the following"

nick
emptydr

and now, I would like to write my script so my script uses each line in the file named listing as the input of the file. How can I do that?

thanks

I think you want the "read" command.

For example, this:
read line1 < filename
reads the first line of "filename" into the variable "line1"

You could do it in a loop in which each invocation of "read" puts a line into an array, indexing the array as you go.

I recommend going to tldp.org and getting the Advanced Bash Scripting Guide. Unless you have a personal forest, don't print it!! I just use it for searches.

Better to use this:
^d means lines beginning with d

and then using result (here I simply use echo to print each line):
