Basically it's like this:
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)
Good morning
I would like kindly to ask you to help me with creation of alias with awk command.
alias a="awk {print $1 "| " $2 "| " $3 "| " $4 "| " $5 "| " $6 "| " $7 "| " $8 "| " $13 "| " }"

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.

unbuffer
UNBUFFER(1) General Commands Manual UNBUFFER(1)NAME
unbuffer - unbuffer output
SYNOPSIS
unbuffer program [ args ]
INTRODUCTION
unbuffer disables the output buffering that occurs when program output is redirected from non-interactive programs. For example, suppose
you are watching the output from a fifo by running it through od and then more.
od -c /tmp/fifo | more
You will not see anything until a full page of output has been produced.
You can disable this automatic buffering as follows:
unbuffer od -c /tmp/fifo | more
Normally, unbuffer does not read from stdin. This simplifies use of unbuffer in some situations. To use unbuffer in a pipeline, use the
-p flag. Example:
process1 | unbuffer -p process2 | process3
CAVEATS
unbuffer -p may appear to work incorrectly if a process feeding input to unbuffer exits. Consider:
process1 | unbuffer -p process2 | process3
If process1 exits, process2 may not yet have finished. It is impossible for unbuffer to know long to wait for process2 and process2 may
not ever finish, for example, if it is a filter. For expediency, unbuffer simply exits when it encounters an EOF from either its input or
process2.
In order to have a version of unbuffer that worked in all situations, an oracle would be necessary. If you want an application-specific
solution, workarounds or hand-coded Expect may be more suitable. For example, the following example shows how to allow grep to finish pro-
cessing when the cat before it finishes first. Using cat to feed grep would never require unbuffer in real life. It is merely a place-
holder for some imaginary process that may or may not finish. Similarly, the final cat at the end of the pipeline is also a placeholder
for another process.
$ cat /tmp/abcdef.log | grep abc | cat
abcdef
xxxabc defxxx
$ cat /tmp/abcdef.log | unbuffer grep abc | cat
$ (cat /tmp/abcdef.log ; sleep 1) | unbuffer grep abc | cat
abcdef
xxxabc defxxx
$
BUGS
The man page is longer than the program.
