Does anything for CentOS 8 provide the function of the fstab-decode utility?
Entries in /proc/mounts and /etc/fstab can have escape sequences for certain special characters, and I need to decode that.
Preface: Never heard of fstab-decode before. Researching the command made me really wonder why it
was invented. Especially since I have never seen an /etc/fstab with "escape sequences" or
"special characters" since at least 1990 (If I am wrong: Please show me such a fstab
file).
So why not just use:
umount $(awk '$3 == "vfat" {print $2}' /etc/fstab)
instead of the seemingly canonical use of fstab-decode
fstab-decode umount $(awk '$3 == "vfat" { print $2 }' /etc/fstab)
Those samples break if the mount point directory name contains spaces, tabs, or
whatever other characters I don't know about that also get represented by
escape sequences. I'm not actually using it with /etc/fstab, but with
/proc/mounts which uses the same convention. I can control /etc/fstab and avoid
the problem, but I cannot control how some auto-mounted foreign filesystem
might be named. I have a script that needs to be robust in the face of such
names.
