ksh has printf, too. And especially, printf "%s\n" "string" works the same everywhere, while "print" requires ksh.

Is there any special reason why you use
Code:
"${some_arbitary_varible}"
instead of
Code:
"$some_arbitary_varible"
?
What if you want to print $some_string_postfix where _postfix is not part of the variable? That will mess up. ${some_string}_postfix will work. { } are just good habits.

The records are variable length and have varying number of fields. A record will have at least two fields, but can have... (9 Replies)

The datafile is here

So, I'm making a little awk script that generates a range-based histogram of a set of numbers. I've stumbled onto a strange thing. Toward the end of the process, I have this test:

In a bash shell, I have to prefix a variable to two .CSV files File1.CSV and File2.CSV. One of the files has a header and the other one is with no header in the below format:

I am confused by the value of "currdisk->currangle" after adding operation. Initially the value of "currdisk->currangle" is 0.77500000000000013, but after adding operation, it's changed to "-nan(0x8000000000000)", Can anyone explain ? Thanks! The following is the occasion of gdb debugging.

PAPS(1) General Commands Manual PAPS(1)NAME
paps - UTF-8 to PostScript converter using Pango
SYNOPSIS
paps [options] files...
DESCRIPTION
paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
through the pango ft2 backend.
OPTIONS
These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is
included below.
--landscape
Landscape output. Default is portrait.
--columns=cl
Number of columns output. Default is 1.
Please notice this option isn't related to the terminal length as in a "80 culums terminal".
--font=desc
Set the font description. Default is Monospace 12.
--rtl Do right to left (RTL) layout.
--paper ps
Choose paper size. Known paper sizes are legal, letter and A4. Default is A4.
Postscript points
Each postscript point equals to 1/72 of an inch. 36 points are 1/2 of an inch.
--bottom-margin=bm
Set bottom margin. Default is 36 postscript points.
--top-margin=tm
Set top margin. Default is 36 postscript points.
--left-margin=lm
Set left margin. Default is 36 postscript points.
--right-margin=rm
Set right margin. Default is 36 postscript points.
--gutter-width=gw
Set gutter width. Default is 40 postscript points.
--help Show summary of options.
--header
Draw page header for each page.
--markup
Interpret the text as pango markup.
--lpi Set the lines per inch. This determines the line spacing.
--cpi Set the characters per inch. This is an alternative method of specifying the font size.
--stretch-chars
Indicates that characters should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
behaviour.
