Check what partition is used? [closed]
Question
I'm working on a SBC6845 card with Linux on it: I have 4 partitions installed:
Creating 5 MTD partitions on "atmel_nand":
0x000000000000-0x000000100000 : "Factory"
0x000000100000-0x000000300000 : "Kernel1"
0x000000300000-0x000000500000 : "Kernel2"
0x000000500000-0x000008280000 : "Rootfs1"
0x000008280000-0x000010000000 : "Rootfs2"
I want to make a shell script that display which partition is currently used but I don't see how.
the command "df -h" returns:
# df -h
Filesystem Size Used Available Use% Mounted on
/dev/root 178.8G 65.4G 104.3G 39% /
tmpfs 61.7M 0 61.7M 0% /dev/shm
tmpfs 61.7M 36.0K 61.7M 0% /tmp
and also fdisk
doesn't work on this system.
Anyone have an idea how to resolve this?
Solution
So you want to know on which partition your script is currently located ? df
can help you with this! You just have to give it the path to your script as an argument:
#!/bin/sh
df $0 | tail -1 | awk '{print $1}'
And sh myscript.sh
gives me: /dev/sda1
Explanations:
df $0
outputs the partition in whichmyscript.sh
istail -1
ignores the first line ofdf
(name of the columns)awk '{print $1}'
returns the first column ofdf
, which is the partition
I hope this is what you expected!
