Methyl -- and anyone else:
It's been a while since I've been here, but I've got something else.
I fooled around with some other scripts and got it to print a message -- are you getting it to display the message?
Here's a script that I did today:
Quote:
trap "echo 'You interrupted me.' " SIGINT
let x=0
while true; do
echo $x
let x=x+1
done
It works fine -- the numbers zip by and get larger and larger. If I hit control - c I can see the message -- it's only a flash. If I put sleep 10 in the script after the echo command,and hit control-c, all I get is ^C displayed on the screen, but no message. I'm wondering if the message is displayed briefly, but so quickly that I can't see it. Am I not typing the command correctly and not noticing it, maybe?
If i try this script
Quote:
trap "echo 'You interrupted me.' " SIGINT
while true; do
echo enter a number
read x
echo $x
done
It works fine. The message is displayed:
Quote:
enter a number
ths
ths
enter a number
^CYou interrupted me.
I think it has something to do with the sleep command, but I can't figure out why. Do you have any ideas?

I'm using the trap command to capture any signals received whilst my script is running.
How's the best way of writing the signal and any other error messages to a file/error log' without having to type '2>$1' on the command line after the script name?

sfind(1) ShapeTools sfind(1)
NAME
sfind - shapeTools RMS recursively descend a system hierarchy
SYNOPSIS
sfind [-subs | -comp] directory [command]
DESCRIPTION
Sfind recursively descends the system hierarchy of a software system managed by the shapeTools Release Management System (shapeTools RMS).
Sfind starts it's search from directory downwards. According to the shapeTools RMS conventions, directory must contain a Shapefile which
lists the subsystems in the variable SUBSYSTEMS and the subsystem components in the variable COMPONENTS. Each subsystem is visited.
If no command is specified, sfind echoes the pathnames of the subsystems it finds, or, if the option -comp is given, the pathnames of the
components of each subsystem.
When a command is given, it is executed in the directory of each subsystem. The string ``{}'' in command is replaced by the pathname of
the subsystem or component.
OPTIONS
-subs command is invoked for each subsystem. This is the default. ``{}'' in command is replaced by the pathname of the subsystem.
-comp command is invoked for each component. ``{}'' in command is replaced by the pathname of the component.
EXAMPLES
List all system components:
sfind -comp ~/development
Show the pathnames of all versionfiles:
sfind ~/development echo -n {}/ ; shape -echo VERSIONFILE
Echo identification of the last release of each subsystem:
sfind ~/development vl -last -format
'$__lastrelease$\n'
`shape -echo VERSIONFILE`
Necessary quoting to echo a pair of curly braces:
sfind ~/development echo two \{\} braces
SEE ALSO
find(1), sh(1), shape(1), shape_RMS(1), shape_tmpl(7)
CAVEATS
Quoting of shell meta characters can be tough.
BUGS
The program is slow because shape(1) is called at least once for each subsystem.
When sfind is interrupted, usually shape(1) displays the message ``shape - interrupted'', which may be confusing.
