For the output file having the line numbers in it's name, I have no good short idea atm. Maybe someone else comes up with it or you try a bit too
We just recently moved from a DG-UX (Unix V) to HP 9000 servers running POSIX. I used the c-shell in the DG-UX system mainly because the bourne-shell did not support aliasing. Now in the default posix-shell of HP aliasing is supported. The main difference seams to be that in a c-shell you can pass... (1 Reply)
Hi all,
I'm trying to define an alias with an embeded awk command:
alias kpipe='kill `psme| grep "ifw -r" | grep -v "grep ifw -r"| awk '{print $2}'`'
The problem is that the awk command (awk '{print $2}') contains two ' ..' quotes. So bash assumes that the first awk quote corresponds to... (5 Replies)

I'd like to define an alias to awk's begin statement since I use awk with different delimiters all the time and it is tiresome to type awk '{OFS="\t";FS="\t"}{BLAH BLAH}' every time. The problem is that bash won't let me make an alias with an open quote, which is necessary for the BEGIN alias to... (3 Replies)
Is there a way to preform check if the parameters that was send with the command awk -f `file_name.awk` `input_file` before even it gets to the BEGIN section (i have tested a try to check in the BEGIN it doesn't let ,you must make it on the section that after the BEGIN) and then decide if the...

Hi to all,
I'm facing some problems when adding an alias like:
#alias list="ls -al | awk '{ print $1, $2, $3, $4, (($5/1048576))"\t", $6, $7, $8, $9 }'"
and when I enter:
#list
I get:
Syntax Error The source line is 1.
The error context is

I am trying to turn this into an alias with no luck. I would then like to put the alias into my bashrc file. I know awk is very picky about quotes. I have tried every version of quotes, single quotes, double quotes, and backslashes that I can think of.

Hi,
I am running the following df command to display df in GB. I am not able to use df -h on this server as that option is not available.

rmvb
rmvb(9F) Kernel Functions for Drivers rmvb(9F)NAME
rmvb - remove a message block from a message
SYNOPSIS
#include <sys/stream.h>
mblk_t *rmvb(mblk_t *mp, mblk_t *bp);
INTERFACE LEVEL
Architecture independent level 1 (DDI/DKI).
PARAMETERS
mp Message from which a block is to be removed. mblk_t is an instance of the
msgb(9S) structure.
bp Message block to be removed.
DESCRIPTION
rmvb() removes a message block (bp) from a message (mp), and returns a pointer to the altered message. The message block is not freed,
merely removed from the message. It is the module or driver's responsibility to free the message block.
RETURN VALUES
If successful, a pointer to the message (minus the removed block) is returned. The pointer is NULL if bp was the only block of the message
before
rmvb() was called. If the designated message block (bp) does not exist, -1 is returned.
CONTEXT
rmvb() can be called from user or interrupt context.
EXAMPLES
This routine removes all zero-length M_DATA message blocks from the given message. For each message block in the message, save the next
message block (line 10). If the current message block is of type M_DATA and has no data in its buffer (line 11), then remove it from the
message (line 12) and free it (line 13). In either case, continue with the next message block in the message (line 16).
