NO.29 In the scripts subdirectory under your home directory there is a file named tstparse.sh. You want to set an Extended ACL so thejsmith user has all permissions to just this file. Which command will accomplish this?

setacl -a user:jsmith:rwx -/scripts/tstparse.sh

extacl -a user=jsmith:rwx -/scripts/tstparse.sh

modacl user=jsmith:rwx -/scripts/tstparse.sh

setfacl -m u:jsmith:rwx -/scripts/tstparse.sh

Explanation
The command that you would use to set an Extended ACL so that the jsmith user has all permissions to just the tstparse.sh file in your scripts subdirectory under your home directory is setfacl -m u:jsmith:rwx
~/scripts/tstparse.sh. This command will modify (or create if it does not exist) the Extended ACL for the specified file and add an entry for the jsmith user with read, write, and execute permissions. You can use getfacl ~/scripts/tstparse.sh to view the Extended ACL for the file.
