I tried to install OpenMotif under Mac OS in the computing lab today, but I got "No mountable file system". Is it because I don't have the administrator's privilege?

The ones on Motif Zone are for MacOS, Linux and FreeBSD only.

In the following code:

awk '
BEGIN{
FS="\t"
OFS="\t"
printf("Enter a glossary term: ")
}


FILENAME=="glossary"{
entry[$1]=$2
next
}

$0 ~ /^(quit|[qQ]|exit|[Xx])$/ {exit}...

Yeah, I have, but never in the Unix environment.

Do I need to install some packages to enable Motif?

I've never been able to execute a single sample program in the book on X programming.

#include <Xm/Xm.h>
#include <Xm/PushB.h>

Widget CreatePushbutton(Widget parent,
char* name,
XtCallbackProc callback,
XtPointer client_data)
{
Widget push;
Arg args[20];
...

OK, I know now, it must be written this way:

BEGIN {FS=" "}
$2~/utah/{
print $2 ", " $1
}

When I changed the second script into the following:

BEGIN {FS=" "}
$2~/utah/
{
print $2 ", " $1
}

The output became:

Why my second script doesn't work?

The second script seems not to work.

I typed "man if" in both TC shell and Bash and I got the exactly same information.
What shell is the command "man" for , anyway?

OK, thanks.
I'm going to drop Tcsh and pick up Bash - so few materials on Tcsh, -:)

I'm a little bit confused about ed. What's the use of ed since there are such more powerful editors like vim, emacs, etc.?

Thanx. I know why now.

If changes have been made in the buffer since the last w
command that wrote the entire buffer, ed will warn the user
if an attempt is made to destroy...

I typed the following commands:

176 lab2-37:~> ed newb.txt
74
1,6p
Hello
Hello World.
I need some sentences to edit.

add the script
OK Fn
2,4c
.
1,3p
Hello
add the script
OK Fn
q
?

I can only use cat to read this file.

It seems that the file sed.txt can not be displayed in Emacs either:


User Commands SED(1)



NAME
sed - manual page for sed version 4.0.3
...

I used the following commands to store the discription of "sed" into a unix file:


man sed > sed.txt


But, after I download the file "sed.txt" to a Windows XP system, the file can not be...

Thanx, it works.

Thanks, it works.

I changed a little bit about the first one, without any effect
255 lab2-36:~/try_direct/another> set x=1; set y=2; set z='expr $x+$y'
256 lab2-36:~/try_direct/another> echo $z
expr $x+$y

The first one does not work:
254 lab2-36:~/try_direct/another> x=1;y=2;z='expr $x + $y'
x=1: Command not found.
y=2: Command not found.
z=expr $x + $y: Command not found.
255...

You've never used TC? Which shell is better, so far as you are concerned?

OK, I see. Thanx a million.
