Difference between two timestamps Contd..
There was this thread earlier with the same name and the solution provided was excellent. Here is the solution to find diffrenc between two timestamp Code:
$ cat timestamp
#! /usr/bin/ksh
echo enter first time stamp
read TIME1
echo enter second time stamp
read TIME2
H1=${TIME1%:+([0-9])}
M1=${TIME1#+([0-9]):}
H2=${TIME2%:+([0-9])}
M2=${TIME2#+([0-9]):}
H1=${H1#0}
M1=${M1#0}
H2=${H2#0}
M2=${M2#0}
((MAM1=H1*60+M1))
((MAM2=H2*60+M2))
((MAM1>MAM2)) && ((MAM2=MAM2+1440))
((diff=MAM2-MAM1))
echo diff = $diff
my problem is, i have excecuted the same code in in AIX box and it works well, but while running this code in solaris i get the following error $ ./Timestamp.sh Start time: 00:13:01 End Time : 06:13:26 ./Timestamp.sh: syntax error at line 18: `H1=${TIME1%:+' unexpected Since the logic used here is excellent, but the problem is due to the Solaris,Any help will be much appreciated on how the H1=${TIME1%:+([0-9])} statement can be changed to run on solaris. Thanks in advance
