The problem however is that I don't have all the folders in the place the script works with.
This naturally results in cannot stat errors.
What I would be interested in now is a way to have the script just ignore any "cannot stat error message".
I know that using a "if-else" would solve the job, but since the code up there is only a small portion of the real thing it simply would be alot of work and writing (or copy and paste if you want) to do.
I hope there is something the mv command has that will help me with that.
I have to read a file line by line, change it and then update the file. Problem is, when i read the file, "read" command ignores leading spaces.
The file is a script which is indented in many places for clarity. How to i make "read" command read leading spaces as well. (3 Replies)

dhclient
DHCLIENT(8) BSD System Manager's Manual DHCLIENT(8)NAME
dhclient -- Dynamic Host Configuration Protocol (DHCP) client
SYNOPSIS
dhclient [-bdqu] [-c file] [-l file] [-p file] interface
DESCRIPTION
The dhclient utility provides a means for configuring network interfaces using DHCP, BOOTP, or if these protocols fail, by statically assign-
ing an address.
The name of the network interface that dhclient should attempt to configure must be specified on the command line.
The options are as follows:
-b Forces dhclient to immediately move to the background.
-c file Specify an alternate location, file, for the configuration file.
-d Forces dhclient to always run as a foreground process. By default, dhclient runs in the foreground until it has configured the
interface, and then will revert to running in the background.
-l file Specify an alternate location, file, for the leases file.
-p file Specify an alternate location for the PID file. The default is /var/run/dhclient.interface.pid.
-q Forces dhclient to be less verbose on startup.
-u Forces dhclient to reject leases with unknown options in them. The default behaviour is to accept such lease offers.
The DHCP protocol allows a host to contact a central server which maintains a list of IP addresses which may be assigned on one or more sub-
nets. A DHCP client may request an address from this pool, and then use it on a temporary basis for communication on the network. The DHCP
protocol also provides a mechanism whereby a client can learn important details about the network to which it is attached, such as the loca-
tion of a default router, the location of a name server, and so on.
On startup, dhclient reads /etc/dhclient.conf for configuration instructions. It then gets a list of all the network interfaces that are
configured in the current system. It then attempts to configure each interface with DHCP.
In order to keep track of leases across system reboots and server restarts, dhclient keeps a list of leases it has been assigned in the
/var/db/dhclient.leases.IFNAME file. IFNAME represents the network interface of the DHCP client (e.g., em0), one for each interface. On
startup, after reading the dhclient.conf(5) file, dhclient reads the leases file to refresh its memory about what leases it has been
assigned.
Old leases are kept around in case the DHCP server is unavailable when dhclient is first invoked (generally during the initial system boot
process). In that event, old leases from the dhclient.leases.IFNAME file which have not yet expired are tested, and if they are determined
to be valid, they are used until either they expire or the DHCP server becomes available.
A mobile host which may sometimes need to access a network on which no DHCP server exists may be preloaded with a lease for a fixed address
on that network. When all attempts to contact a DHCP server have failed, dhclient will try to validate the static lease, and if it succeeds,
it will use that lease until it is restarted.
A mobile host may also travel to some networks on which DHCP is not available but BOOTP is. In that case, it may be advantageous to arrange
with the network administrator for an entry on the BOOTP database, so that the host can boot quickly on that network rather than cycling
through the list of old leases.
NOTES
You must have the Berkeley Packet Filter (BPF) configured in your kernel. The dhclient utility requires at least one /dev/bpf* device for
each broadcast network interface that is attached to your system. See bpf(4) for more information.
