Linux
K2 Edge uses the Linux operating system. In this section we will cover a number of Linux commands
which we will use during this training.
On older systems, replace the /system directory with the /publitronic directory.
Command Example Usage Description when used and with option
grep grep ‘text’
file.txt text search and filter – can be combined with other
commands using pipe |
ls ls –l lists files in the current directory (-l gives long listing)
ls ls –l |grep pt adding the pipe symbol (|) and grep, filters the result (in this
case by pt)
cd cd /system change to the specified directory
man man ls shows a manual for the command (in this case ls)
ifconfig shows network configuration
