Top Forums UNIX for Dummies Questions & Answers 'awk' help for script to clean out wireless. Post 302931118 by Lord Lien on Saturday 10th of January 2015 07:24:37 PM

This is what I get when I run the script. The awk command is not passing back "This Is A Test". Its passing back only single words, so my script its trying to delete the wireless "This", "Is", "A", "Test" that don't exist. (Ignore the "preferred networks on en1")


Code:
Lord:Desktop administrator$ sudo ./wireless\ clean\ up.sh 
Deleting Preferred
Network Preferred was not found in the preferred networks list
Deleting networks
Network networks was not found in the preferred networks list
Deleting on
Network on was not found in the preferred networks list
Deleting en1:
Network en1: was not found in the preferred networks list
Deleting This
Network This was not found in the preferred networks list
Deleting is
Network is was not found in the preferred networks list
Deleting a
Network a was not found in the preferred networks list
Deleting test
Network test was not found in the preferred networks list
Network This is a test is already in the preferred networks list
Lord:Desktop administrator$

I did try using this command :-

Code:
networksetup -listpreferredwirelessnetworks en1 > wireless.txt

in slightly modified code & using awk to read the file but it kept error out on the 1st line.

NAME
networks - network name database SYNOPSIS
/etc/inet/networks /etc/networks DESCRIPTION
The networks file is a local source of information regarding the networks which comprise the Internet. The networks file can be used in conjunction with, or instead of, other networks sources, including the NIS maps networks.byname and networks.byaddr and the NIS+ table networks. Programs use the getnetbyname(3SOCKET) routines to access this information. The network file has a single line for each network, with the following information: official-network-name network-number aliases Items are separated by any number of SPACE or TAB characters. A `#' indicates the beginning of a comment. Characters up to the end of the line are not interpreted by routines which search the file. This file is normally created from the official network database maintained at the Network Information Control Center (NIC), though local changes may be required to bring it up to date regarding unofficial aliases and/or unknown networks. Network numbers may be specified in the conventional dot (`.') notation using the inet_network routine from the Internet address manipula- tion library, inet(7P). Network names may contain any printable character other than a field delimiter, NEWLINE, or comment character. SEE ALSO
getnetbyaddr(3SOCKET), getnetbyname(3SOCKET), inet(3SOCKET), nsswitch.conf(4), inet(7P) NOTES
The official SVR4 name of the networks file is /etc/inet/networks. The symbolic link /etc/networks exists for BSD compatibility. The network number in networks database is the host address shifted to the right by the number of 0 bits in the address mask. For example, for the address 24.132.47.86 that has a mask of fffffe00, its network number is 803351. This is obtained when the address is shifted right by 9 bits. The address maps to 12.66.23. The trailing 0 bits should not be specified. The network number here is different from that described in netmasks(4). For this example, the entry in netmasks would be 24.132.46.0 fffffe00.
