Substring in Shell Script
Hi
I'm new to Shell scripting. Someone please help me in extracting a portion of string from a file.
Eg:
I got a file like, Readme.txt and has the following name value pairs
input1 : /homes/input1/
input2 : /homes/input2/
...
...
When I give the parameter input1, the value /homes/input1/ has to returned from the file and get stored in a variable.
Thanks in advance.

hwloc-assembler
HWLOC-ASSEMBLER(1) hwloc HWLOC-ASSEMBLER(1)
NAME
hwloc-assembler - Assemble multiple XML topologies
SYNOPSIS
hwloc-assembler [options] output.xml [--name <name1>] input1.xml [--name <name2>] input2.xml ...
OPTIONS
-n --name <name>
Set <name> in the AssemblerName info attribute of the next input topology root to ease identification within the final global topol-
ogy.
-f --force
Ignore errors while reading input files.
-v --verbose
Verbose messages.
DESCRIPTION
hwloc-assembler combines the input XML topologies and exports the resulting global topologies to a new XML file. All inputs are inserting
as children of the global root object. Each input topology root is annotated with info attributes before insertion. AssemblerIndex is set
to the index within the list of inputs. AssemblerName is set to the name given with --name if any. hwloc-assembler-remote offers a fron-
tend for assembling remote nodes topologies without having to manually gather and transfer each of them.
EXAMPLES
To assemble two nodes topologies:
$ hwloc-assembler output.xml --name host1 host1.xml --name host2 host2.xml
RETURN VALUE
Upon successful execution, hwloc-assembler returns 0.
hwloc-assembler will return nonzero if any kind of error occurs, such as (but not limited to) failure to parse the command line.
