Kill the process *group* containing a process named svscan (djb's daemontools)

Daemontools[1] won't always properly reap it's children. Sometimes when you need to kill the main svscan process, you want to also clean up all of it's children. The way to do that is to send a signal to the entire process group. It is a bit tricky [1] http://cr.yp.to/daemontools.html

Copy the most recent wav file from /media/ to the current folder

Watch out if you have several USB drives plugged in: it scans the whole /media/ folder !!! You can replace /media/ by the path of a specific USB drive (something like /media/F77A-530B/) I use a sound recorder and I want to plug the recorder and grab the most recent sound. That's what this command does. Use mv instead of cp to move instead of copy. Change *.wav to the required file type.

rclone - include Service account blobs to your config

For easy portability you can include you service account blobs directly to your rclone config. So it generate a rclone config like the following: [dst977] type = drive scope = drive service_account_credentials = {"type":"service_account","project_id":"saf-ju66hcgi8qf8zidhvfww4oxwe7","private[.................] }

Dump android contacts, sms

Crude, but works. Note for security, /data/ will be inaccessible unless your device has been *rooted*. On the other hand, if a device has been rooted, its data is now wide open to anyone with a USB cable and the above "one-liner". `adb` is one of the platform tools in the android SDK. To get SMS messages: $ adb pull /data/data/com.android.providers.telephony/databases/mmssms.db ; sqlite3 -batch

Quick and dirty RSS

runs an rss feed through sed replacing the closing tags with newlines and the opening tags with white space making it readable.

'readlink' equivalent using shell commands, and following all links

This is a equivalent to the GNU ' readlink' tool, but it supports following all the links, even in different directories. An interesting alternative is this one, that gets the path of the destination file $ myreadlink() { [ ! -h "$1" ] && echo "$1" || (local link="$(expr "$(command ls -ld -- "$1")" : '.*-> $.*$$')"; cd $(dirname $1); myreadlink "$link" | sed "s|^$[^/].*$\$|$(dirname $1)/\1|"); }
