Top Forums Shell Programming and Scripting Failure using regex with awk in 'while read file' loop Post 302940532 by pathunkathunk on Tuesday 7th of April 2015 01:08:07 AM

This successfully extracts lines with the correct label. But I am looking for only two lines for each label in labels.txt, and the lines should be randomly chosen. Can this script be piped to " gshuf -n 2"--or the equivalent--before the file is created?

What does $3 do in this code?

APT-SPY.CONF(5) 						File Formats Manual						   APT-SPY.CONF(5)

NAME
apt-spy.conf - configuration file for apt-spy(8) DESCRIPTION
apt-spy.conf is the configuration file for apt-spy(8). It consists of a series of area labels, followed by a list of countries belonging to that label. Whitespace is ignored. Comments may be added anywhere, and begin with the hash ('#') character. Once a hash character is encountered, the rest of the line is ignored. A label consists of any alphanumeric characters, and ends with a colon character (':'). The label must be on a line by itself (excluding comments). Following a label are a list of country codes (one per line) of countries belonging to that label. Each country has a unique two-letter country code corresponding to its top level domain identifier. This is the same as the ISO3166 code. You can find the country code for a specific country either by looking at /var/lib/apt-spy/mirrors.txt, or by looking at the commented examples in the default apt-spy.conf. Labels cannot exist within labels. The end of a label section is signaled by the start of a new one, or by the end of file. Any valid label existing in apt-spy.conf can be specified to apt-spy using the '-a' option. apt-spy will then proceed to benchmark the mirrors in the list of countries associated with that label. EXAMPLES
This is an example of a valid apt-spy.conf file: USUK: GB # United Kingdom US # United States Australia: AU France-Germany-Netherlands: FR DE NL There is a default configuration file included with apt-spy. For further examples, and for a list of valid country codes, please refer to this. SEE ALSO
