How to store the file name in a single line??
hi,
i have a variable, in which i am storing the file names that are present in the current directory.
Code:
$ls -1
s1.txt
s2.txt
s3.txt

$FILES=`ls -ltr | grep "^-" | awk '{print $NF}'`
$echo $FILES
s1.txt
s2.txt
s3.txt

i want to store the files names in a single line in the variable FILES delimited by a space.
eg
Code:
$echo $FILES
s1.txt s2.txt s3.txt

is there a way??

Simply run ls without any options:
Code:
FILES="$( ls )"

OR
Code:
FILES="$( ls *.txt )"

ls will take directory also.. n there can be other type of files also..

Code:
FILES=$( ls -ltr | awk '/^-/{$0=$NF;ORS=FS;print}' )

or
FILES=$( ls -ltr | awk '/^-/{ORS=FS;print $NF}' )

Code:
FILES=$(find -name \*.txt -printf "%f ")

# 7

Code:
FILES=$(find -maxdepth 1 -type f -name \*.txt)

I recommend to store them like this - newline separated!
You have the option to convert to a space-separated list on the fly
Code:
set -f; echo $FILES
for file in FILES; do
