Script question

Alex Lavrov. — Mon, 07 Mar 2005 10:34:14 GMT

Hello,
I want to know what are the standart ways to format the output of the script?

For explamle I need the following output:

Mount Size Comments
/opt 345 Testing bla
/software/omni 8003 bla bla bla

If I use printf(1) to format the output, it's only padding from the left and I need padding from the right, is there any way to tell printf to pad from the right?

(I'm using onl bash, no perl, php etc ...)

Not sure what layout you want, as the HP ITRC code strips away multiple spaces in your post.

But the format argument of bash's printf allows for a '-' sign to indicate right alignment and a figure to indicate field width.

Example

bash$ printf "%14d\n" 12
............12

AND

bash$ printf "%-14d" 12
12............

I've replaced the spaces with '.'s to show you what is happening.

printf will pad in either direction. Some combination of the following example will work for you:

printf "%20s%-20s%-20.20s\n" AA BB CC

The "-" pads on the right, -20.20 pads on the right but also limits the total width of the field to 20 so that it can both pad and truncate.

I don't know about bash, but ksh has the following features:

typeset -L var1 # var1 is Left-justified, remove leading spaces
typeset -R var2 # var2 is Right-justified, remove trailing spaces
typeset -L8 var3 # var3 is Left-justified, padded to 8 chars total, remove leading spaces
typeset -R9 var4 # var4 is Right-justified, padded to 9 chars total, remove trailing spaces
