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

  • No - its a hobby-project to create a list of all French Verb conjugations from a large list of French verbs. – user191960 Oct 22 '09 at 05:55

    @ghostdog74 - How could you doubt me? You've been helping me for a couple of days ;) with text manipulation under *nix systems. I guess the question does look a bit homeworky - but I made it so that others may benefit via my abstraction. Else I could've just plugged in what I wanted. – user191960 Oct 22 '09 at 06:05

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

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

  • Worked perfectly! As did those below - but included files with odd characters (apostrophes). Should've put that in the question - but I tried to abstract it as much as possible. – user191960 Oct 22 '09 at 06:18

normally i would ask what have you tried.

while read -r line 
do 
   command ${line} > ${line}.txt
done< "file"
