using string manipulation
Hi,

Indeed it is easy (after spending hours and hours and hours ...)
You can use string manipulation to achieve your objective via:

Code:
new_dir=${the_dir%/bin*}

Essentially, it matches /bin and anything after that hence the * and returns the left of the string that was not matched.

check-zone-expiration

CHECK-ZONE-EXPIRATION(1p)				User Contributed Perl Documentation				 CHECK-ZONE-EXPIRATION(1p)

NAME

       check-zone-expiration

SYNOPSIS

       # check-zone-expiration dnssec-tools.org paypal.com dnssec-tools.org    will expire in 26 days, 2 hours, 16 minutes, 36 seconds paypal.com
       will expire in 12 days, 17 hours, 7 minutes, 1 second

       # check-zone-expiration -m 1123200 dnssec-tools.org paypal.com paypal.com	  will expire in 12 days, 17 hours, 6 minutes, 22 seconds

DESCRIPTION

       The check-zone-exiration script reports how long until a zone will expire by querying for the zone's (top level) RRSIG and calculating how
       much time is left before the signatures will no longer be valid.  It will then report how much time is left in human readable form.

       If the -m switch is provided with a time argument (in seconds), it will only print output for zones that have less than that time left.

OPTIONS

       -m STRING
       --minimum-reporting=STRING
	   Minimum reporting time, or else be silent for the zone
