Let's create a file:
$ dd if=/dev/zero of=/tmp/x bs=1000000 count=1 status=none
$ ls -ldog /tmp/x
-rw-r--r-- 1 1000000 Jun 6 08:32 /tmp/x
Now, somehow I want to punch holes into it, use -p:
$ ./fallocate -p /tmp/x
fallocate: no length argument specified
Well, okay then try with -l:
$ ./fallocate -p -l 10000 /tmp/x
fallocate: only -n mode can be used with --zero-range
Huh? I didn't specify neither -n nor -z.
Well, let's try -n then:
$ ./fallocate -p -n /tmp/x
fallocate: no length argument specified
Reading 'man fallocate' regarding --punch doesn't help either:
-p, --punch-hole
Punch holes in the file, the range should not
exceed the length of the file.
What does "punching" mean? Please explain without using the
word "punch".
And how would one specify a "range"? There's no option with
such a "range" argument.
Finally, please add some examples to the man page.
Thanks!
