3rd command

"grep -sc '$USER' * | grep -v ':0' | sort -k 2 -t : -r" will not work when files name contain :0 symbols, to solve this just replace grep -v ':0' to grep -v ':0$'

2nd paragraph in the testconnect.sh output

The descriptions states that 3 pings are sent at 2 second intervals but the command in the testconnect.sh script is:

PINGS=`pint -c 1 -i 2 [your gateway] | wc -l`

which should be:

PINGS=`pint -c 3 -i 2 [your gateway] | wc -l`

if you want three pings.

3rd paragraph

The second sentence in the paragraph says:

By counting the number of letters (with wc -l) and applying a length test

The command wc -l gives the number of lines in each input file is written to the standard output. The word letters needs to be replaced with lines.
