Search and Replace
I am trying to search and replace using two different files with strict search rules.
One file contain some data and the other file contain some numbers as shown below.
DataFile.txt
HTML Code:
>L1_T1
text data...
text data..
>L1_T1
text data...
text data..
>L1_T1
text data...
text data..
.....
.....
>L1_T2
text data...
text data..
>L1_T2
text data...
text data..
...
... upto
>L7_T8
text data...
text data..
>L7_T8
text data...
text data..
data header ranges from L1_T1 .. L1_T8 .. upto L7_T8 (56 headers altogether)
NumberFile.txt
HTML Code:
1
3
4
7
8
75
86
...
...
4025
4030
4032
I want to replace the headers(L*_T*) of DataFile using the numbers from the NumberFile. However, the condition is each header has a particular range to take the numbers and one number can't be used twice. For Example:
L1_T1 can take those available numbers within the range 1 - 72
L1_T2 can take those available numbers within the range 73 - 144
L1_T3 can take those available numbers within the range 144 - 216
....
L1_T8 can take those available numbers within the range 505 - 576
....
...
L7_T8 can take those available numbers within the range 3961 - 4032
(Increment of 72 for each increasing Header)
Example Output for the above data can be:
HTML Code:
>1
text data...
text data..
>3
text data...
text data..
>7
text data...
text data..
.....
.....
>75
text data...
text data..
>86
text data...
text data..
...
...
>4030
text data...
text data..
>4032
text data...
text data..
Thanks for any help.

plock(3C) Standard C Library Functions plock(3C)
NAME
plock - lock or unlock into memory process, text, or data
SYNOPSIS
#include <sys/lock.h>
int plock(int op);
DESCRIPTION
The plock() function allows the calling process to lock or unlock into memory its text segment (text lock), its data segment (data lock),
or both its text and data segments (process lock). Locked segments are immune to all routine swapping. The effective user ID of the calling
process must be super-user to use this call.
The plock() function performs the function specified by op:
PROCLOCK Lock text and data segments into memory (process lock).
TXTLOCK Lock text segment into memory (text lock).
DATLOCK Lock data segment into memory (data lock).
UNLOCK Remove locks.
RETURN VALUES
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
The plock() function fails and does not perform the requested operation if:
EAGAIN Not enough memory.
EINVAL The op argument is equal to PROCLOCK and a process lock, a text lock, or a data lock already exists on the calling process; the op
argument is equal to TXTLOCK and a text lock or a process lock already exists on the calling process; the op argument is equal to
DATLOCK and a data lock or a process lock already exists on the calling process; or the op argument is equal to UNLOCK and no lock
exists on the calling process.
EPERM The {PRIV_PROC_LOCK_MEMORY} privilege is not asserted in the effective set of the calling process.
USAGE
The mlock(3C) and mlockall(3C) functions are the preferred interfaces for process locking.
