UNIX Desktop Questions & Answers

I tried to explain this earlier, but did a poor job of it. So I am trying again but taking a different approach.....

I have a file called test_words. In this file I have one line with 5 three letter words, with a single space seperating the words.(I.e., "cat car mop red pin")

I want to create a script that will read the file and loop each word individually into a command until all words in the file have been used. Use the echo command for arguements sake.

the output would look like this:

cat
car
mop
red
pin

The file test_word may change, by adding words or subtracting words, but always use a space as the delimiter.

can anyone help with this?

Thank you in advance for any and all help on this.

Something like this?

Code:

sed 's/ /\n/g' file

Regards

Thank you for helping with seperating it, Franklin, but how to put it in a loop to run a command with each word? that is where I really need the help.

Try:

tr ' ' '\n' <file |sed "s/^/$CMND /" | sh

The above pipe-lined command will put $CMND (i.e. whatever is in CMND variable) before each word as one per line and then will execute all of them, again in sequence.

I hope this is what you wanted to do.

Code:

for word in $(<file)
do
   echo your_cmd_goes_here $word
done

...remove the echo and put your command in place of "your_cmd_goes_here"

Shamrock, Thank you that worked perfect!!!! Sham-rocks!!

Thank you all, for your help.

for some reason I could not get it to work with what unilover suggested. not sure why but here is the command that worked with Shamrock.


for word in $(<file)
do response=command {$word is located within command}
echo
echo "$response"
echo "$response" >> ./return-data
file=return-data
done

cat "$file" | lpr
echo "All data has been sent to the following file."
echo "file"
echo "Script complete."



Thanks a million all. And I am sorry for posting in two forums. I did not get a sponse, so I thought it was ok, to post in an advance forum. Again, sorry, I am a newb to this forum.
