delete line in a file
Hi all,
I would like to delete a line in file.txt which has a list of filename.
example:
file_a
file_b
file_c
lets say i have file_b in my directory, then i should delete file_b in file.txt and get output file.txt with only file_a and file_b.
Below is my script, my result is still
file_a
file_b
file_c
Anyone can help???
#!/bin/bash
while read line
do
if [[ -r $line ]]
then
sed -e '/$line/d' $1 > $1.tmp
mv $1.tmp $1
else
echo "file not readable"
fi
done < $1
