Can I use a list of file names that I saved to file to have each file on the list copied/moved/deleted?
How can I use cp rm or mv commands to manipulate files saved to a list, for example one made like so:
ls Downloads/ | grep example > example.tmp
The point is to be able to view/edit the file list in a file editor before making a final manipulation, and then deleting the tmp.
So for example, the following does not work:
mkdir example_dir && cp -t example_dir < example.tmp
Is there a way that I could make this work?
Once I get that down, I'd like to simplify the whole process into fewer commands, but... I'm just trying to make it work (and see how it will work at this individual step) first.
command-line rm mv cp batch

Use bash's command substitution:
$ ls -1
1
2
3
a
b
c
Put only a, b, c into a list file.
$ ls -1 | grep -E "^[a-z]$" > list
$ cat list
a
b
c
Edit the list file if you like, then copy the files:
$ mkdir foo
$ cp $(cat list) -t foo
$ ls foo/
a b c

would you mind if I asked you what the syntax"^[a-z]$"refers to specifically with what each part means? I understand all of the rest of your solution. Thank you.

We are looking for a set of characters, ^ means started with, [a-z] means from a to z (any of them), $: ended with the same character. It looks for all lines containing a character from a to z.
