Shell Programming and Scripting

Hello forum members,

I am writing a script to two tasks.
1: displaying the list of the files in the current directory.
2: removing the specifed file from the list.
I have written a sample script ,so can u please verfiy and correct.

echo Enter list of files
ls *.txt
read textfile
rm -f $textfile
if [ $textfile ]
then
echo failed to remove file.
else
echo removed sucessfully.
fi

I am looking forward from you.......ASAP.

Advance thanks,
Siva Ranganath CH.

This is rather simple ...
try below:

Code:

#!/bin/ksh
src=`pwd`
cd $src
rc=`ls -lrt|rm -f $1`
if [[ $rc -eq 0 ]]
then
echo "$1 successfully removed"
else
echo "could not remove $1"
fi

you have to pass teh file name that you want to delete as a parameter to this script and it will be removed

Re-ordering the commands and adding more validation.

Code:

echo "List of files"
ls *.txt 2>/dev/null
echo ""
echo "Enter filename of file to remove"
read textfile

if [ ! -f "${textfile}" ]
then
    echo "File does not exist: ${textfile}"
    exit
fi

rm -f "${textfile}"

if [ -f "${textfile}" ]
then
    echo "Failed to remove file"
else
    echo "Removed sucessfully"
fi

ls -1 *.txt| while read line
do
rm -f $line
if [ -s $line ] ; then
echo "failed to remove"
else
echo "removed successfully"
fi
done
