Top Forums Shell Programming and Scripting Assigning values to an array via for/while loop Post 302261467 by fiori_musicali on Monday 24th of November 2008 09:07:41 PM

Code:
for i in 1 2 3 4 5; do
      arr[$i]=$(awk 'NR=="$i" { print $2 }' file_with_5_records)
done

Got that far.

So YES: my syntax was incorrect to begin with. I've been dabbling with programming so little that I still have trouble remembering that = is an assignment and not a comparison.

The script still doesn't do what I want because AWK doesn't know the value of $i. I need to pass it to AWK somehow, or come up with a different approach.

Any tips/workarounds...??

I'm really looking forward to getting stuck at some more profound obstacles...

extract_font_range(3alleg4)					  Allegro manual				       extract_font_range(3alleg4)

NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library. SYNOPSIS
#include <allegro.h> FONT *extract_font_range(FONT *f, int begin, int end) DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the font. Example: FONT *myfont; FONT *capitals; FONT *fontcopy; ... /* Create a font of only capital letters */ capitals = extract_font_range(myfont, 'A', 'Z'); /* Create a copy of the font */ fontcopy = extract_font_range(myfont, -1, -1); ... destroy_font(capitals); destroy_font(fontcopy); RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks. SEE ALSO
