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

bash, linux, loops, scripting, unix

Solution

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

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

Problem

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 ```
