[SOLVED] Subshell multiline output

timbCFCA · 08-30-2010, 01:19 PM

I'm putting together a small bash script which uses diff in a sub shell.
RESULT=$(diff file1 file2)

This is the first time I've tried to return multiline output from a subshell - how can I get this to display as multiple lines instead of one?

Also, looping breaks at every word not every line.

Re Q2: be nice to see an example, but I think you need the IFS variable http://tldp.org/LDP/Bash-Beginners-G...ml#table_03_01 & 11.7 here http://tldp.org/LDP/abs/html/loops1.html

The assignment shown does put multiple lines in $RESULT. How are you displaying the value of $RESULT?

Code:

c@CW9:~/d$ result=$(diff /tmp/trash[12])
c@CW9:~/d$ echo "$result"
2,3c2,3
< def
< ghi
---
> deF
> ghI
c@CW9:~/d$ echo $result
2,3c2,3 < def < ghi --- > deF > ghI

Thanks gentlemen. The quoting on the echo fixed my issue.
I would have sworn I already tried that but I guess not. Thanks for being an extra set of eyes.
