How to echo space or tab delimited values into rows?

Hi,

I have the following code:

Code:
LIST=`ls | grep '.sql$'`
echo $LIST

The above code will give me something like..

Code:
file1.sh file2.sh file3.sh file4.sh file5.sh

I want to display the values into rows using echo like...

Code:
file1.sh
file2.sh
file3.sh
file4.sh
file5.sh

If it's not possible with echo, then what other command can I use.

Thanks.

Quoting "$LIST" will preserve the ls output format:

Code:
echo "$LIST"

You could just as easily use ls *.sql, than using grep (except possibly when a very, very large number of files is involved).

try with below code
Code:
list=`ls *.sh`
echo $list | tr -s '\040' '\012'

Cheers

That really isn't a flexible solution.

Code:
$ touch a.sh b.sh "c d".sh

$ ls -1
a.sh
b.sh
c d.sh

$ list=`ls *.sh`

$ echo $list | tr -s '\040' '\012'
a.sh
b.sh
c
d.sh

# whereas, ...
$ echo "$list"
a.sh
b.sh
c d.sh
# gives the correct output without tr

I think generally the file names are not space separated
Moreover the reply was in context of the file names mentioned above in the first post
So for that case above will work fine

Never presume mate.

You never know what all those applications and programers will spit out on filesystem.
I have seen terrible things, from not getting the desired solution with your code, to restoring thousands of files from tape cause of bad shell expansion.
