Hi some quick thought on the last code snippet:
In awk the middle section is processed per line, so you should leave out: for(i=1;i<=NR;i++)
The results should be stored in arrays so they can be used in the END section.
The END section contains code after all lines have been read in the middle section,
so the following has no business there:
I want to find the top N entries for a certain field based on the values of another field.
For example if N=3, we want the 3 best values for each entry:
Entry1 ||| 100
Entry1 ||| 95
Entry1 ||| 30
Entry1 ||| 80
Entry1 ||| 50
Entry2 ||| 40
Entry2 ||| 20
Entry2 ||| 10
Entry2 ||| 50... (1 Reply)

Hi everybody,

In the tab-delimeted input file below I am trying to use awk to update the value in $2 if TYPE=ins in bold, by adding the value of
HRUN= in italics. In the below since in line 1 TYPE=ins the 117282541 value in $2 has 6 added because that is the value of HRUN=.
Hopefully the awk is a start but I... (2 Replies)
I am trying to output a tab-delimited result that uses the data from a tab-delimited file to combine and subtract specific lines.
If $4 matches in each line then the first matching sequential $6 value is added to $2, unless the value is 1, then the original $2 is used (like in the case of line... (3 Replies)

ns_masterunlock
Ns_Master(3aolserver) AOLserver Library Procedures Ns_Master(3aolserver)__________________________________________________________________________________________________________________________________________________NAME
Ns_MasterLock, Ns_MasterUnlock - Enter and leave the single master critical section lock
SYNOPSIS
#include "ns.h"
void
Ns_MasterLock(void)
void
Ns_MasterUnlock(void)
_________________________________________________________________DESCRIPTION
The single master critical section lock is used throughout the core server to protect portions of code from being run by more than one
thread at a time. These are convenience functions which actually make calls to Ns_CsEnter and Ns_CsLeave to perform the locking and unlock-
ing function.
You should not use these functions in your modules. To protect critical sections in your modules you should create and initialize your own
named locks, then wrap your critical sections with calls to Ns_CsEnter and Ns_CsLeave.
Ns_MasterLock()
Enter the single master lock. The thread that holds this lock is guaranteed exclusive access to the section of code that follows the
call to Ns_MasterLock. Other threads that attempt to enter the master critical section while another thread owns the master lock
will block until the owning thread releases the master lock.
Be extremely careful with code you place within the master critical section. If the thread that owns the master lock blocks for any
reason while in the master critical section, other threads that need to enter that section of code will block until the master lock
is released.
Ns_MasterUnlock()
Leave the single master critical section. The thread that owns the lock must release it after the critical section of code has com-
pleted so that other threads may execute the critical section code.
