Top Forums Shell Programming and Scripting Fdisk and grep command not working in udev trigger Post 303023188 by Scott on Wednesday 12th of September 2018 06:50:47 PM

Looking at the output(mount /media/usb/test), DEVNAME is not set. It looks like the previous fdisk command is not returning anything. What is fdisk -l |grep FAT16 |awk '{print $1}' returning if you run it manually?

If DEVNAME isn't set, the mount command won't know which device to mount, and will look in the fstab / mtab for /media/usb/test to figure out what to do.

MOUNT.NFS(8)						      System Manager's Manual						      MOUNT.NFS(8)

NAME
mount.nfs, mount.nfs4 - mount a Network File System SYNOPSIS
mount.nfs remotetarget dir [-rvVwfnsh ] [-o options] DESCRIPTION
mount.nfs is a part of nfs(5) utilities package, which provides NFS client functionality. mount.nfs is meant to be used by the mount(8) command for mounting NFS shares. This subcommand, however, can also be used as a standalone command with limited functionality. remotetarget is a server share usually in the form of servername:/path/to/share. dir is the directory on which the file system is to be mounted. Under Linux 2.6.32 and later kernel versions, mount.nfs can mount all NFS file system versions. Under earlier Linux kernel versions, mount.nfs4 must be used for mounting NFSv4 file systems while mount.nfs must be used for NFSv3 and v2. OPTIONS
-r Mount file system readonly. -v Be verbose. -V Print version. -w Mount file system read-write. -f Fake mount. Don't actually call the mount system call. -n Do not update /etc/mtab. By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip making an entry. -s Tolerate sloppy mount options rather than fail. -h Print help message. nfsoptions Refer to nfs(5) or mount(8) manual pages. NOTE
For further information please refer nfs(5) and mount(8) manual pages. FILES
