Reading File line by line - Issue
I am trying to read the below file line by line for the below operation
i) extract the directory alone and assign it one variable
ii) extract the permission available in the line and add comma between the permissions and assign to another variable
iii) Finally apply setfacl logic as shown in the output.

File - bkp_23.txt
*******************
Code:
# file:  /disk1/script_1/ user::rwx group::r-x group:service:r-x mask::r-x other::r-x
# file:  /disk1/script_1//hello.txt user::rw- group::r-- other::r--
# file:  /disk1/script_1//bkp_10.txt user::rwx group::r-x other::r-x

My Code :
**********
Code:
#!/bin/sh
input="bkp_23.txt"
while IFS= read -r line;
do
echo $line
file_name=`sed -e 's/# file:\(.*\)/\1/g' "$line" | awk '{print $1}'`
echo $file_name
file_perm=`sed -e 's/# file:\(.*\)/\1/g' "$line" | awk '{$1=""}{print}' | tr ' ' ',' | awk '{sub(",","")}1'`
echo $file_perm
echo "setfacl -m "$file_perm" "$file_name" executing"
done <"$input"

Output:
*********
Code:
setfacl -m user::rwx,group::r-x,group:service:r-x,mask::r-x,other::r-x  /disk1/script_1/
setfacl -m  user::rw-,group::r--,other::r--  /disk1/script_1//hello.txt
setfacl -m  user::rwx,group::r-x,other::r-x   /disk1/script_1//bkp_10.txt

But ending up with error :
Code:
sed: can't read # file: /disk1/script_1/ user::rwx group::r-x group:service:r-x mask::r-x other::r-x: No such file or directory
