Look for a program named 'xev' or one named 'showkey' as examples.

Hi!

If you are planning to implement the code in a C program, you can use the CURSES.H library, or the TERMIO.H library

#include < stdio.h >
#include < curses.h >

main()
{
int ch;

initscr();
ch = getch();
endwin();

printf(" %d\n", ch);
}

If you are not familier with CURSES.H library, refer the man pages on the same to learn more of it. The above is the simplest of programs presented.

Hi Shaik,
I tried the code which got me some messages that i could not understand.
could you please look into that.

I ran it on HPUX B.11.00
The message is as follows..

/usr/ccs/bin/ld: Unsatisfied symbols:
stdscr (data)
wgetch (code)
initscr (code)
endwin (code)

Those routines are in the curses library. When you compile you need to do something like:
cc whatever.c -lcurses -o whatever

Hi All.
I am still a beginner in Unix.I have got one program.i am not getting the solution for one program.Will anybody help me soon.

Q.write a C program which accepts a valid directory name as a command line argument and list all the files in the given diirectory as well as all the files in subsequent directories.(The solution can be recursive or non-recursive).

  I need the solution immediately.I need it desperately within 15th Jan.
