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???

if [[ -r $line ]]
then
sed -e '/$line/d' $1 > $1.tmp
mv $1.tmp $1
else
echo "file not readable"
fi
done < $1

NAME
ecaccess-file-move - Move or Rename ECaccess Files SYNOPSIS
ecaccess-file-move -version|-help|-manual ecaccess-file-move [-debug] source-ecaccess-file target-ecaccess-file DESCRIPTION
Allow moving an ECaccess File. When the move occurs within the same ECaccess File System then it is a rename. When the move occurs across two different ECaccess File Systems then first a copy is done and then a delete of the original file is done (e.g. similar to ecaccess- file-copy ... -erase). The source-ecaccess-file and target-ecaccess-file are in the form [domain:][/user-id/]path. Please read the "Shell commands -> File Management" section of the "ecaccess" guide for more information on the ECaccess File System. ARGUMENTS
source-ecaccess-file The source ECaccess File name. target-ecaccess-file The target ECaccess File name. OPTIONS
-version Display version number and exits. -help Print a brief help message and exits. -manual Prints the manual page and exits. -debug Display the SOAP messages exchanged. EXAMPLES
ecaccess-file-move ec:test1.txt ec:test2.txt Rename the test1.txt file in the ECFS directory of the authenticated user in test2.txt. ecaccess-file-move ec:test1.txt home:test2.txt Copy the test1.txt file from the ECFS directory of the authenticated user to the test2.txt file in the $HOME directory of the authenticated user, then delete the test1.txt file from ECFS.
