There is a lot of services that will print public IP like ipgive.me. Using curl or wget you can easily print your current public IP on the terminal.
curl ipgive.me
wget -q -O- ipgive.meI had a special script that removes e-mail from Trash after 90 days. But one day I was looking for a message older than 7 days and realized that older messages are no longer in trash!
I checked Roundcube settings, but it does not have such option. There is only an option to delete all messages from after logout.
Auto expunge can be configured in dovecot, but there was not such configuration:
doveconf | grep expungePeople on the internet were pointing to mail clients like Thunderbird. After some more digging I found out the iPhone by default has such setting! OMG!!!
You need to go to your mail account advanced settings on your iPhone.
In Ubuntu you can hibernate your PC by using the following command:
sudo systemctl hibernateThe problem is it does not automatically lock the screen. To lock the screen use:
xdg-screensaver lockNow we can combine it together:
xdg-screensaver lock && systemctl hibernateNote that you will need to enable your user to execute systemctl hibernate without sudo. You can do it by editing /etc/sudoers. Just add:
your-username ALL= NOPASSWD: /usr/bin/systemctl hibernateThis script will call Doveadm-Expunge based on users in home directory.
#!/bin/bash
FOLDERS=/home/*
for f in $FOLDERS
do
doveadm expunge -u "$(basename $f)" mailbox Spam savedbefore 14d;
doveadm expunge -u "$(basename $f)" mailbox Trash savedbefore 7d;
done
This script will start soffice headless listening on port 8100. You can use it eg. with JODConverter.
#!/bin/bash
# openoffice.org headless server script
#
# chkconfig: 2345 80 30
# description: headless openoffice server script
# processname: openoffice
#
OOo_HOME=/usr/bin
SOFFICE_PATH=$OOo_HOME/soffice
PIDFILE=/var/run/openoffice-server.pid
set -e
case "$1" in
start)
if [ -f $PIDFILE ]; then
echo "OpenOffice headless server has already started."
sleep 5
exit
fi
echo "Starting OpenOffice headless server"
$SOFFICE_PATH -nologo -nodefault -norestore -nocrashreport -nolockcheck -headless -nofirststartwizard -accept="socket,host=localhost,port=8100;urp" & > /dev/null 2>&1
touch $PIDFILE
;;
stop)
if [ -f $PIDFILE ]; then
echo "Stopping OpenOffice headless server."
killall -9 soffice && killall -9 soffice.bin
rm -f $PIDFILE
exit
fi
echo "Openoffice headless server is not running."
exit
;;
*)
echo "Usage: $0 {start|stop}"
exit 1
esac
exit 0
For the past three days I was trying to rescue a damaged disk of my colleague. I already knew about a great disk cloning tool called ddrescue in Linux. So this was the first step I did. After 20 hours of work the clone has been created, but with some errors during read. I was hoping that I will be able to boot from it after I put it back to the PC, but in this case there was some problem with the partition table, so Windows has not been even be able to recognize it as NTFS, even though Linux did!
I didn’t want to reinstall the system after so much hours spend on this, so I was looking for some other tools which could help me save the disk. There was a lot of suggestions on using some paid software, but I don’t have good experience with them.
Finally I found another great open source software called TestDisk. It is a command line tool, but I don’t care much if it helps 🙂 Using this software I was able to recreate the partition table, after it found the lost NTFS partition and as soon as I restarted PC, Windows finally fixed the NTFS using chkdsk.
I have finally found a solution for my problem described in older post. Today I have found out that you can run Wuala without GUI. To do this you have to call wuala with the following parameter.
wuala -nogui
But only this is not enough. You have to also login to your account, because Wuala won’t auto login in this case. I have created a bash script which runs Wuala and as soon as it is initialized it logs you in.
#!/bin/sh
# Run Wuala with no GUI
wuala -nogui &
# Give Wuala some time to initialize
sleep 30
# Login
wuala login USERNAME PASSWORD
Change USERNAME and PASSWORD with your credentials and save this piece of code to /usr/bin/start-wuala.sh. Make it executable by calling sudo a+x /usr/bin/start-wuala.sh. After that you can put it to Startup Applications. But before you do that, you should setup your synchronization, because when Wuala starts in background you are not able to start another instance. To shutdown existing instance go to terminal and execute wuala shutdown.
You can also check status of the background process on the following address: http://127.0.0.1:33333/.
Today I came across a very little command which will create playlist based on files in current folder. I just had to put it to my blog.
It is very easy. Open terminal. Go to desired directory and execute this:
ls *.mp3 |sort > playlist.m3u
Files are also automatically sorted by name.
