Top Forums Shell Programming and Scripting to perform checks line by line on a file Post 302229784 by era on Thursday 28th of August 2008 02:36:02 AM

Assuming the line numbers are not part of the file, you are removing the directory name but leaving a leading slash. This is probably not what you want. (Why would you want to remove the first directory component anyway?) The trivial fix is to use cut -c6- but I suspect you could get a quite different script if you told us why you are doing this and what you are ultimately trying to achieve.

update-service(8)					      System Manager's Manual						 update-service(8)

NAME
update-service - add/remove a service to/from system-wide service supervision SYNOPSIS
update-service --add|--remove service-directory [service-name] update-service --list|--check [service-name] DESCRIPTION
service-directory must be a directory to be used by supervise(8), service-name must not start with a dot, and must not contain a slash. update-service adds or removes the service-directory to the system-wide service supervision provided through daemontools' svscan(8), lists all registered system-wide services, or checks for a specific service-name whether it is registered. When adding a service, and the service-directory resides in /etc/, update-service makes sure that the ./supervise/ subdirectories in the service-directory, and the optional service-directory/log/, are symbolic links pointing into /var/lib/supervise/, unless they already are symbolic links. OPTIONS
--add | -a Add the service directory service-directory to the system-wide service supervision, under the name service-name. If service-name is not specified, update-service will use the basename of service-directory. You can use the svc(8) program to control the newly added service, and the svstat(8) program to query its status, e.g.: # svstat /etc/service/service-name --remove | -r Remove the service directory service-directory, which has been added under the name service-name, from the system-wide service supervision. If service-name is not specified, update-service will use the basename of service-directory. When removing the ser- vice-directory, the exit command is sent to the corresponding supervise(8) process, telling it to take the service down and exit afterwards. You can use the svc(8) and svstat(8) programs to control the removed service, or query its status, e.g.: # svstat service-directory --list | -l If service-name is specified, update-service checks whether service-name is registered as system-wide service, prints a message and exits non-zero if not, or prints the service-name and the directory it points to and exits zero if yes. If service-name is not specified, it prints the names of all system-widely registered services, one per line. --check | -c The same as --list, but update-service doesn't print anything to standard out or standard error. ENVIRONMENT
SVDIR The environment variable $SVDIR overrides the default services directory /etc/service/. FILES
