[Rkhunter-users] -eq: unary operator expected errors in 1.3.0

[Steve Z. <st...@gm...>]

I'm receiving the following errors when I run rkhunter:

 Checking application versions...

    Checking version of GnuPG                                [ OK ]

 I've seen a couple of other similar issues reported and in most cases
 the submitters have been asked to run 'rkhunter --debug --enable
 apps'.  The pertinent information seems to be:

 + APPLICATION=php
 ++ echo php%PHP%Warning:
 ++ cut -d% -f2
 + APPLICATION_DESC=PHP
 ++ echo php%PHP%Warning:
 ++ cut -d% -f3
 + VERSION=Warning:
 + '[' -z Warning: ']'
 + '[' Warning: = -1 ']'
 ++ echo php%PHP%Warning:
 ++ cut -d% -f4
 + ISBAD=
 + '[' -eq -1 ']'
 /usr/bin/rkhunter: line 10015: [: -eq: unary operator expected
 + '[' -eq 1 ']'
 /usr/bin/rkhunter: line 10018: [: -eq: unary operator expected
 + display --to SCREEN+LOG --type PLAIN --result OK --color GREEN
 --log-indent 2 --screen-indent 4 APPS_CHECK PHP

 Any suggestions for what do to to fix this?  I can send the entire log
 file if that will help - just let me know who to send it to.

 Thanks,
