removing frame charecters
Hi
I have a requirement as follows. My Input file is as follows.
COL1,COL2,COL3,COL4,COL5
987,2,3~7~5,400~468~598,0005~4687~5980
1111,2,2~7,400~468,0005~897
Expected OUTPUT
============
COL1,COL2,COL3,COL4,COL5
987,2,3,400,0005
987,2,7,468,4687
987,2,5,598,5980
1111,2,2,400,0005
1111,2,7,468,897
COL3,COL4 and COL5 are in turn having own sub division with ~ as delimiter. COL3 can have any number of records till 80. If COL3 has 4 records then COL4 and COL5 contains same number of records.That is COL3 is dynamic.This can be done by counting and cutting columns in loop. But,How can this be done using some array structure to make it faster.

RENICE(8) BSD System Manager's Manual RENICE(8)
NAME
renice -- alter priority of running processes
SYNOPSIS
renice priority [[-p] pid ...] [[-g] pgrp ...] [[-u] user ...]
renice -n increment [[-p] pid ...] [[-g] pgrp ...] [[-u] user ...]
DESCRIPTION
The renice utility alters the scheduling priority of one or more running processes. The following who parameters are interpreted as process
ID's, process group ID's, user ID's or user names. The renice'ing of a process group causes all processes in the process group to have their
scheduling priority altered. The renice'ing of a user causes all processes owned by the user to have their scheduling priority altered. By
default, the processes to be affected are specified by their process ID's.
The following options are available:
-g Force who parameters to be interpreted as process group ID's.
-n Instead of changing the specified processes to the given priority, interpret the following argument as an increment to be applied to
the current priority of each process.
-u Force the who parameters to be interpreted as user names or user ID's.
-p Reset the who interpretation to be (the default) process ID's.
For example,
renice +1 987 -u daemon root -p 32
would change the priority of process ID's 987 and 32, and all processes owned by users daemon and root.
Users other than the super-user may only alter the priority of processes they own, and can only monotonically increase their ``nice value''
within the range 0 to PRIO_MAX (20). (This prevents overriding administrative fiats.) The super-user may alter the priority of any process
and set the priority to any value in the range PRIO_MIN (-20) to PRIO_MAX. Useful priorities are: 20 (the affected processes will run at the
lowest priority), 0 (the ``base'' scheduling priority), anything negative (lower values cause more favorable scheduling).
FILES
/etc/passwd to map user names to user ID's
SEE ALSO
nice(1), getpriority(2), setpriority(2)
STANDARDS
The renice utility conforms to IEEE Std 1003.1-2001 (``POSIX.1'').
HISTORY
The renice utility appeared in 4.0BSD.
BUGS
Non super-users cannot increase scheduling priorities of their own processes, even if they were the ones that decreased the priorities in the
first place.
