Ls -ltr in scripting
Hi All,

I wrote below script

for i in `ls`
do
echo "list of files $i"
done

but i want display as like ls -ltr,it's displaying as one column

Use for i in $(ls -ltr), then, abandoning the deprecated `...` nomenclature.

Sure you need the -tr?

Use \n in the echo statement

It is not clear, what you want to achieve.. Your loop puts "list of files" in front of every filename. This would show an ls -ltr version of that:
Code:
ls -ltr | sed 's/^/list of files /'

But that is probably not what you are looking for ...

Assuming Scrutinizer guessed correctly at the output you want, and that you don't mind changing the value of IFS in your script, you could get by without sed:
Code:
# Note: There is nothing but a <newline> character between the single quotes
# on the following two lines.  You could use IFS=$'\n' with a recent bash or ksh.
IFS='
'
for i in $(ls -ltr)
do	printf 'List of files %s\n' "$i"
done

Or, if you need to preserve and restore IFS:
Code:
IFS_set=${IFS-unset}
IFS_old=${IFS}
# Note: There is nothing but a <newline> character between the single quotes
# on the following two lines.  You could use IFS=$'\n' with a recent bash or ksh.
IFS='
'
for i in $(ls -ltr)
do	printf 'List of files %s\n' "$i"
done
if [ "$IFS_set" = "unset" ]
then	unset IFS
else	IFS=$IFS_old
fi

Both of the above produce output like:
Code:
List of files total 16
List of files -rw-r--r--  1 dwc  staff  330 Jun 13 23:37 problem
List of files -rwxr-xr-x  1 dwc  staff  182 Jun 13 23:38 tester

Think of your problem and adapt. As you were attempting to use builtins then 'KIS', (Keep It Simple).
