Of bash and whitespace...

lev_lafayette · #1 (**permalink**) 04-11-2008

Hmmm... Bash doesn't parse whitespace with a read.

Code:

lev@sys09:~$ read line; echo "$line"
 test
test

You can imagine what this does if you're using a shell script to read a list of unknown file names containing unknown spaces.

Code:

lev@sys09:~$ read word1 word2; echo "$word1,$word2"
123 456 789
123,456 789

Anyone have a solution for this?

Change the value of $IFS temporarily.

Thank you. That worked perfectly. I owe you a beer.
