Use bash to read a file and then execute a command from the words extracted

Question

FILE:

hello
world

I would like to use a scripting language (BASH) to execute a command that reads each WORD in the FILE above and then plugs it into a command.

It then loops to the next word in the list (each word on new line). It stops when it reaches the end of the FILE.

---

Progression would be similar to this:

Read first WORD from FILE above

Plug word into command

command WORD > WORD

• which will output it to a text file; with word as the name of the file.

Repeat this process, but with next to nth WORD (each on a new line).

Terminate process upon reaching the end of FILE above.

---

Result of BASH command on FILE above:

hello:

RESULT OF COMMAND UPON WORD hello

world:

RESULT OF COMMAND UPON WORD world

Answer 1

You can use the "for" loop to do this. something like..

for WORD in `cat FILE`
do
   echo $WORD
   command $WORD > $WORD
done
