Re: Bash script stops after 5 minutes

Thanks, I haven't got my head around the systemd.service, it doesn't seem well documented for the less-technical (like me!), but yes the link that you provided does appear to be the issue.
I don't however understand what links the service file to the script. Is it ExecStart?

Bash script stops after 5 minutes

I have written a bash script (as part of a bigger project) which is run via a init.d process following a system reboot. The script is intended to just run once, and is then deleted, but some of the commands in the script take a long time to execute - such as extending the partition filesystem (resiz...

Rounding in a bash script

I'm writing a bash script which provides data about the SD card, and I've run into this issue. (sorry if it's a basic mistake) If I run; $sudo blockdev --getsz /dev/mmcblk0 I get the correct answer - 15130624 But if I combine it with some calculations; DISK_SIZE="$(($(sudo blockdev --getsz /dev/mmcb...

Re: Combining commands in bash script

Yes I'm aware of that, but as I want the logs to be in tmpfs, I would still need to create empty log files with the correct permissions set for MySQL to write to, as it can't create them itself. Same with Redis.

Re: Combining commands in bash script

Tmpfs appears to mount ok, but the issues are that MYSQL expects to find the /var/log/mysql folder structure and also it's mysql.log & error.log files. If they are not present, MySQL cannot create them and errors. Same applies with Redis. I want to get the logs into tmpfs to extend the life of a sys...

Re: Combining commands in bash script

What if the command requires a value, such as 'chown mysql:adm' or requires sudo to execute?
I don't seem to get that working despite putting the command within double quotes ""sudo chown mysql:adm""

Combining commands in bash script

I'm creating a rc.local script to create directories, empty files & permissions in a tmpfs volume, and found that I've got each command on a separate line. Is there a way I can combine commands, similar to: $ sudo mkdir /var/log/{redis,apache2,mysql} (I tried that and it didn't work!) sudo mkdir /va...

Unhandled prefetch abort: breakpoint debug exception (0x002)

I'm wanting to replace my RP v1 with a RP v2. My v1 raspberry Pi is running Raspbian, and has its root moved to a USB HDD, and it runs quite a bit of software, so if possible I would like to avoid a new OS installation if at all possible. To prepare the v1 OS for moving to a v2 device, I ran; sudo a...

Re: Raspberry Pi 2 upgrade

Yes, I am using the GPIO as I have a small adapter board fitted which uses a Hope RFM12B chip to receive/transmit 868mhz data from environmental sensors (temperature, humidity etc) which is then processed by the Pi, and published on my website. I've contacted the maker of the board who has confirmed...

That sounds interesting, and having searched through some 'Jessie' forum posts, it seems that a lot have also changed over.

Apache v2.4

Apache 2.4 was released in July, yet v2.2 is still the default package for Raspberry Pi's. Is there a reason for this (I see on apache.org that they list v2.2 & v2.4 as current versions).

I ask because I'm interested in some of the new security features introduced in v2.4.
