Hi
I would like to extract the first portion of filename from a list of files.
The filename pattern is of the form 123456789_TEXT_TEXT_TEXT_.csv. I want to extract just the numerical portion of this filename from the list of files and then output this into another text file.

sysctl
SYSCTL(8)SYSCTL(8)NAME
sysctl - configure kernel parameters at runtime
SYNOPSIS
sysctl [-n] [-e] variable ...
sysctl [-n] [-e] [-q] -w variable=value ...
sysctl [-n] [-e] [-q] -p [filename]
sysctl [-n] [-e] -a
sysctl [-n] [-e] -A
DESCRIPTION
sysctl is used to modify kernel parameters at runtime. The parameters available are those listed under /proc/sys/. Procfs is required for
sysctl support in Linux. You can use sysctl to both read and write sysctl data.
PARAMETERS
variable
The name of a key to read from. An example is kernel.ostype. The '/' separator is also accepted in place of a '.'.
variable=value
To set a key, use the form variable=value where variable is the key and value is the value to set it to. If the value contains
quotes or characters which are parsed by the shell, you may need to enclose the value in double quotes. This requires the -w param-
eter to use.
-n Use this option to disable printing of the key name when printing values.
-e Use this option to ignore errors about unknown keys.
-N Use this option to only print the names. It may be useful with shells that have programmable completion.
-q Use this option to not display the values set to stdout.
-w Use this option when you want to change a sysctl setting.
-p Load in sysctl settings from the file specified or /etc/sysctl.conf if none given. Specifying - as filename means reading data from
standard input.
-a Display all values currently available.
-A Display all values currently available in table form.
EXAMPLES
/sbin/sysctl -a
/sbin/sysctl -n kernel.hostname
/sbin/sysctl -w kernel.domainname="example.com"
/sbin/sysctl -p /etc/sysctl.conf
FILES
/proc/sys
/etc/sysctl.conf
SEE ALSO sysctl.conf(5)BUGS
The -A parameter behaves just as -a does.
