Unlock your KDE4 session over SSH

So this first obtains address of the DBUS session, as it's not available by default over SSH. Then it tells plasma-overlay to exit. `kquitapp` is pretty much an equivalent of the qdbus calls.

This is a specialized command for Ericsson CS5.2 - Getting the test case trace on SDP

This command allows to follow up a trace on SDP (CS5.2), at the same time as the trace records are stored in the file with "raw" format.

Trace files in native format are useful to filter the records before to translation from '|' to '\n'.

Example:

grep -v OP_GET <raw-records>.trace | tr '|' '\n'

Grep auth log and print ip of attackers

Find the failed lines, reverse the output because I only see 3 indicators after the IP address, i.e. port, port#, ssh2 (in my file), cut to the 4th field (yes, you could awk '{print $4}'), reverse the output back to normal and then sort -u (for uniq, or sort | uniq).

grep an array item, like a_var[11], in a file

Just want to show the "+" usage in the grep command. And if using egrep, thing would be a little bit easier:

grep -n "arrname\[[[:digit:]]+\]" filename
