/etc/mnttab - table of the mounted file systems

The /etc/mnttab file contains details of all the file systems mounted on the local computer. This file contains information which is generated by the mount command.

Each line contains the following information, which is separated by an arbitrary number of blanks and/or tabulators:

Format

resource

mountp

fstype

spec-options

time

resource

Absolute path name of the mounted file system or, in the case of bs2fs file systems, mounted BS2000 files in wildcard syntax.

For bs2fs file systems the entry differs from the specification in the mount command as follows:

• • • It is converted completely into uppercase notation

    • Characters to be escaped are displayed without the associated escape character

Example:

mount –F bs2fs –o ftyp=text :v70a:\$bach.sys\* /home/bach/bs2.1

generates the following entry in /etc/mnttab:

:V70A:$BACH.SYS* /home/bach/bs2.1 bs2fs ftyp=text ...

mountp

Absolute path name of the mount point.

fstype

File system type.

spec-options

Options as specified in the mount command.

time

Mount time, specified in seconds since 1/1/1970

Entries in the /etc/mnttab file are deleted again if the umount or umountall command is executed for corresponding file systems or file system types.

Example

Enter the following in the POSIX shell: cat /etc/mnttab
