Question Need to split a string
Hi,

We have a SunOS 5.10 Generic_142900-13 sun4v sparc SUNW,T5240.

I'm trying to find a way to split a string into 2 variables.

Ex:
parm1="192.168.1.101/parent/child"

What I need to do is split the string above into:

host="192.168.1.101"
location="parent/child"

I saw the solution provided here https://www.unix.com/shell-programmin...tion-file.html but somehow we don't have the -o option for grep as I keep getting illegal option --o.

The purpose of this is for a shell script already created to do an FTP function. Originally it was intended for accepting HOST, USER, PASS and FILE parameters only. Basically file goes to whatever the main directory on FTP connect. Now users are passing HOST/folder as value for HOST parameter which gives out an error now since 192.168.1.101/parent/child is not a valid HOST. And it would be a lot of work to add another parameter for LOCATION because a lot of other programs are already using this script so I'm trying to avoid this solution for now.

I'd appreciate any suggestions.

Thanks.

tgt-setup-lun(8)					      System Manager's Manual						  tgt-setup-lun(8)

NAME

       tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target

SYNOPSIS

       tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h]

DESCRIPTION

       Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows:
       iqn.2001-04.com.<hostname>-<target_name> The target name must be unique.

       The  script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia-
       tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator.

EXAMPLES

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82

       Create a target that uses /dev/sdb1 and allows connections from any initiator:
       tgt-setup-lun -d /dev/sdb1 -n my_target

       Display help:
       tgt-setup-lun -h
