Alias problem with awk command
Hi to all,
I'm facing some problems when adding an alias like:
Code:
#alias list="ls -al | awk '{ print $1, $2, $3, $4, (($5/1048576))"\t", $6, $7, $8, $9 }'"

and when I enter:
Code:
#list

I get:

Code:
Syntax Error The source line is 1.
 The error context is
                { print >>>  , <<< 
 awk: 0602-502 The statement cannot be correctly parsed. The source line is 1.


I'm running ksh Version M-11/16/88f on AIX version 5.3
Can you tell where the problem can be?
Thanks
Enid

The shell is evaluating $1, $2, etc, when you create the alias, not when you use it.

Try:
Code:
alias list="ls -al | awk '{ print \$1, \$2, \$3, \$4, ((\$5/1048576))\"\t\", \$6, \$7, \$8, \$9 }'"

(I tried with other combinations of quoting, but that didn't seem to work).

Not tested on AIX, but I can't imagine the syntax would be any different.

In fact, I will move this thread from the AIX sub-forum to the Shell Scripting sub-forum.

Thanks scottn,

it worked pretty well on AIX (also on Ubuntu).

Regards.

Sometimes it's easier - and more flexible - creating a function, or a script, instead of using aliases.

But glad it works Smilie
