Hello,
when I call my awk script, I keep getting an error :
sam@sam-laptop:~/shell/td4$ awk -f agenda.awk -- -n Robert agenda.txt
awk: agenda.awk:6: printf "Hello"
awk: agenda.awk:6: ^ syntax error
the script contains this :
#!/usr/bin/awk
BEGIN {
}
printf "Hello"
END {
}
Thank you

Which I would like to return as
ccc

Hi all,
I have an associative array in awk that gets populated like this...
chr_count[$3]++
When I try to print my chr_counts I use this:
for (i in chr_count) {
print i,":",chr_count[i];
}
But not surprisingly, the order of i is not sorted in any way.
Is there an easy way to iterate over…

When I run a program from the console, e.g.
me@box:~$ firefox
I expect the console to log error messages (I think this is std out or std err?) and other items from the program, firefox in this case.
But today I notice that bash just opens the program and goes to a new prompt, e.g.
me@box:~$…

First login process name seems to be set to "-bash", but if I subshell then it becomes "bash". for example:
root@nowere:~# echo $0
-bash
root@nowere:~# bash
root@nowere:~# echo $0
bash
-bash is causing some scripts to fail, such as . /usr/share/debconf/confmodule
exec /usr/share/debconf/frontend…
