/var/log mounted in tmpfs

[rossoreed]

I'm writing a script which will be used on Raspberry Pi's that will be configured in 2 ways;
a) Pi's that are have /var/log mounted on a physical drive
b) Pi's that have their /var/log mounted as tmpfs
I need a conditional statement that will differentiate between the 2, so if /var/log is mounted in tmpfs - the script will run, but if mounted on a physical drive then it wont.

To achieve this;

if /var/log = tmpfs {
...run my script
}

Any help would be appreciated.

You don't say what language this is to be scripted in, but I'll assume Bash

Code: Select all

if ( mount | grep "on /var/log "| grep -q "^tmpfs " )
then
  echo "/var/log is tmpfs"
fi

rpdom, sorry it's taken so long to reply, but thanks, that's a great solution and it works very well.
Exactly what I was looking for.
