Here are a couple of ways to do it:
Code:
#!/bin/bash
echo 'processing datfile1 using while loop:'
while read x
do      if [ "$x" -gt 16000 ]
        then    printf "%d\n" "$x"
        fi
done < datfile1
echo 'processing datfile2 using awk:'
awk '$1 > 16000' datfile2

If datfile1 contains:
Code:
1
2
4
6
7       
8       
12
24996
24999

and datfile2 contains:
Code:
1
3
5
6
8       
9       
12
24999
25000

the output produced is:
Code:
processing datfile1 using while loop:
24996
24999
processing datfile2 using awk:
24999
25000

If you are running this on a Solaris system, use /usr/xpg4/bin/awk, /usr/xpg6/bin/awk, or nawk instead of /bin/awk or /usr/bin/awk.

Although this was written using bash (as you requested), this script will work with any shell that recognizes basic Bourne shell syntax.

shishi_ticket_set_enc_part

shishi_ticket_set_enc_part(3)					      shishi					     shishi_ticket_set_enc_part(3)

NAME

       shishi_ticket_set_enc_part - API function

SYNOPSIS

       #include <shishi.h>

       int shishi_ticket_set_enc_part(Shishi * handle, Shishi_asn1 ticket, int32_t etype, uint32_t kvno, const char * buf, size_t buflen);

ARGUMENTS

       Shishi * handle
		   shishi handle as allocated by shishi_init().

       Shishi_asn1 ticket
		   Ticket to add enc-part field to.

       int32_t etype
		   encryption type used to encrypt enc-part.

       uint32_t kvno
		   key version number.

       const char * buf
		   input array with encrypted enc-part.

       size_t buflen
		   size of input array with encrypted enc-part.

DESCRIPTION

       Set  the  encrypted  enc-part  field  in  the Ticket.  The encrypted data is usually created by calling shishi_encrypt() on the DER encoded
       enc-part.  To save time, you may want to use shishi_ticket_add_enc_part() instead, which calculates the encrypted data and calls this func-
       tion in one step.

RETURN VALUE

       Returns SHISHI_OK iff successful.
