How do I check what version of syslinux I have?


We installed from sources,

$ strings syslinux | grep SYSLINUX
SYSLINUX
SYSLINUX 3.72 2008-09-25

Try with

rpm -qf $(type -p syslinux)

Since you're using CentOS, you can see what version of the RPM you have installed.

[user@host ~]$ which syslinux
/usr/bin/syslinux
[user@host ~]$ rpm -qf /usr/bin/syslinux
syslinux-3.11-4
