[gentoo-user] where is 'mke2fs' ?

[gentoo-user] where is 'mke2fs' ?

[Philip Webb]

I need to rewrite the filesystem on a USB stick after it got damaged.
My notes tell me to use 'mke2fs', but 'which' doesn't find it :
has it been replaced by something else ?
I have 'e2fsprogs' installed, but there's no 'man' file for it
& it doesn't seem to create filesystems.
There is a utility 'sys-fs/genext2fs', which I emerged & looked at,
but it's not clear whether it does the simple job I need.

Can anyone advise ?

You have the right package, mke2fs is inside it:

$ equery f sys-fs/e2fsprogs ... /sbin/mke2fs /sbin/mkfs.ext2 -> mke2fs 
/sbin/mkfs.ext3 -> mke2fs /sbin/mkfs.ext4 -> mke2fs

Here man page is installed
$ man mke2fs

And which/whereis also:

$ which mke2fs
/sbin/mke2fs

$ whereis mke2fs
mke2fs: /sbin/mke2fs /usr/share/man/man8/mke2fs.8.bz2

# equery b `which mke2fs`
 * Searching for /sbin/mke2fs ...
sys-fs/e2fsprogs-1.46.5-r4 (/sbin/mke2fs)

Might it be hidden behind USE="tools"?

This is correct.

$ equery uses e2fsprogs
...
+ + tools       : Build extfs tools (mke2fs, e2fsck, tune2fs, etc.) 

Philip, make sure you have the 'tools' USE flag enabled for e2fsprogs
and it should be available in /sbin/

On my system, /sbin/mke2fs is part of sys-fs/e2fsprogs-2.46.5-r3 with 
the tools USE FLAG set.

Does your PATH perhaps simply not contain /sbin ?  Some people do that for...  reasons...

In addition to this, you might also want to take a look at "e-file", 
which comes from the package "app-portage/pfl" in order to find parent

That's funny. I forgot from which package the binary file "e-file" came 
from, so I used "e-file" to determine its origin. :D

Yes : sometime ago the 'tools' flag must have been introduced
& since I don't format devices often, it didn't trip me up till now.
I've updated my notes.

I formatted the stick, copied the files it had before the damage,
then discovered that it was in fact physically bad,
so 'mke2fs' wasn't needed today.  I used another formatted stick instead.

Thanx to both + Jack as well.
