variable assignment using awk
Guys,
Could you please help me out. I need two values in two variables using awk from the o/p of grep.
example:-
grep sdosanjh <filename>
sdosanjh myhostname myfilename
NOW WHAT I WANT IS :-
sdosanjh should be in variable (say NAME)
myhostname should be in variable (say HOSTNAME)
3rd coloumn i am not bothered about.
Can you please suggest if we can do this by pipe the output of grep to awk ?
I tried the following but not able to get the value of val1 using echo.
grep sdosanjh <filename> | awk '{val=$1}{val1=$2}{print val, val1}'
Because my next line will be making a ssh connection with the myhostname
i.e. ssh $val1 [Something like that]

Seriously, though, is there any practical difference? I was... (3 Replies)

load_dat_font
load_dat_font(3alleg4) Allegro manual load_dat_font(3alleg4)
NAME
load_dat_font - Loads a FONT from an Allegro datafile.
SYNOPSIS
#include <allegro.h>
FONT *load_dat_font(const char *filename, RGB *pal, void *param)
DESCRIPTION
Loads a FONT from an Allegro datafile. You can set param parameter to point to an array that holds two strings that identify the font and
the palette in the datafile by name. The first string in this list is the name of the font. You can pass NULL here to just load the first
font found in the datafile. The second string can be used to specify the name of the palette associated with the font. This is only
returned if the pal parameter is not NULL. If you pass NULL for the name of the palette, the last palette found before the font was found
is returned. You can also pass NULL for param, which is treated as if you had passed NULL for both strings separately. In this case, the
function will simply load the first font it finds from the datafile and the palette that precedes it.
For example, suppose you have a datafile named `fonts.dat' with the following contents:
FONT FONT_1_DATA
FONT FONT_2_DATA
FONT FONT_3_DATA
PAL FONT_1_PALETTE
PAL FONT_2_PALETTE
Then the following code will load FONT_1_DATA as a FONT and return FONT_1_PALETTE as the palette:
FONT *f;
PALETTE pal;
char *names[] = { "FONT_1_DATA", "FONT_1_PALETTE" }
f = load_dat_font("fonts.dat", pal, names);
If instead you want to load the second font, FONT_2, from the datafile, you would use:
FONT *f;
PALETTE pal;
char *names[] = { "FONT_2_DATA", "FONT_2_PALETTE" }
f = load_dat_font("fonts.dat", pal, names);
If you want to load the third font, but not bother with a palette, use:
FONT *f;
char *names[] = { "FONT_3_DATA", NULL }
f = load_dat_font("fonts.dat", NULL, names);
RETURN VALUE
Returns a pointer to the font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to
avoid memory leaks.
