I don't know if you're still following this thread but I found a way to efficiently use both your ideas.
Because the sentence was read as a string (not an array), I had no other way than using alister's idea:

At that point, radoulov's idea was interesting because it left the for loop open to any statement:

I am trying to strip all leading and trailing spaces of a shell variable using either awk or sed or any other utility, however unscuccessful and need your help.

Hi,
I have a problem with expending variables when used in a for loop:
#!/bin/ksh
VAR1=aaa
VAR2=bbb
VAR3=ccc
for ITEM in VAR1 VAR2 VAR3
do
echo "${ITEM}"
done
This gives:
VAR1
VAR2

Hi,
Again a little problem.
Do not understand good why an empty string is not detected.
Here is the program:
#!/bin/ksh
APR=`date | grep Apr | awk '{print $2$3}'`
MAY=`date | grep May | awk '{print $2$3}'`
JUN=`date | grep Jun | awk '{print $2$3}'`
echo "Variable Apr has value:... (6 Replies)
Hello All,
This question is actually for the service console of VMware ESX 3.5 but is relevant to this forum I think. I have been advised to use the following commands:

Hello
I am having issues with a script I'm working on developing on a Solaris machine.
The script is intended to find out how many times a particular user (by given userid) has logged into the local system for more than one hour today.

Hi Guys,
I'm trying to find all files with a particular extension and then loop some actions. The problem is that if the files have spaces in their names I get end up being each word as a separate result rather than the entire file.

nmea(n) NMEA protocol implementation nmea(n)

nmea - Process NMEA data
SYNOPSIS
package require Tcl 8.4
package require nmea ?1.0.0?
::nmea::input sentence
::nmea::open_port port ?speed?
::nmea::close_port
::nmea::configure_port settings
::nmea::open_file file ?rate?

::nmea::do_line
::nmea::rate
::nmea::log ?file?
::nmea::checksum data
::nmea::write sentence data
::nmea::event setence ?command?
_________________________________________________________________DESCRIPTION
This package provides a standard interface for writing software which recieves NMEA standard input data. It allows for reading data from
COM ports, files, or programmatic input. It also supports the checksumming and logging of incoming data. After parsing, input is dis-
patched to user defined handler commands for processing. To define a handler, see the event command. There are no GPS specific functions
in this package. NMEA data consists of a sentence type, followed by a list of data.
COMMANDS
::nmea::input sentence
Processes and dispatches the supplied sentence. If sentence contains no commas it is treated as a Tcl list, otherwise it must be
standard comma delimited NMEA data, with an optional checksum and leading $.
nmea::input {$GPGSA,A,3,04,05,,09,12,,,24,,,,,2.5,1.3,2.1*39}
nmea::input [list GPGSA A 3 04 05 09 12 "" "" 24 "" "" "" 2.5 1.3 2.1]
::nmea::open_port port ?speed?
Open the specified COM port and read NMEA sentences when available. Port speed is set to 4800bps by default or to speed.
::nmea::close_port
Close the com port connection if one is open.
::nmea::configure_port settings
Changes the current port settings. settings has the same format as fconfigure -mode.
::nmea::open_file file ?rate?
Open file file and read NMEA sentences, one per line, at the rate specified by ?rate? in milliseconds. The file format may omit the
leading $ and/or the checksum. If rate is <= 0 (the default) then lines will only be processed when a call to do_line is made.
::nmea::close_file
Close the open file if one exists.
::nmea::do_line
If there is a currently open file, this command will read and process a single line from it. Returns the number of lines read.
::nmea::rate
Sets the rate at which lines are processed from the open file, in milliseconds. The rate remains consistant across files, there does
not need to be a file currently open to use this command. Set to 0 to disable automatic line processing.
::nmea::log ?file?
Starts or stops input logging. If a file name is specified then all NMEA data recieved on the open port will be logged to the ?file?
in append mode. If file is an empty string then any logging will be stopped. If no file is specified then returns a boolean value
indicating if logging is currently enabled. Data written to the port by write, data read from files, or input made using input, is
not logged.
::nmea::checksum data
Returns the checksum of the supplied data.
::nmea::write sentence data
If there is a currently open port, this command will write the specified sentence and data to the port in proper NMEA checksummed
format.
::nmea::event setence ?command?
Registers a handler proc for a given NMEA sentence. There may be at most one handler per sentence, any existing handler is replaced.
If no command is specified, returns the name of the current handler for the given setence or an empty string if none exists. In
addition to the incoming sentences there are 2 builtin types, EOF and DEFAULT. The handler for the DEFAULT setence is invoked if
there is not a specific handler for that sentence. The EOF handler is invoked when End Of File is reached on the open file or port.
The handler procedures, with the exception of the builtin types,must take exactly one argument, which is a list of the data values.
The DEFAULT handler should have two arguments, the sentence type and the data values. The EOF handler has no arguments.
nmea::event gpgsa parse_sat_detail
nmea::event default handle_unknown
proc parse_sat_detail {data} {
puts [lindex $data 1]
}
proc handle_unknown {name data} {
puts "unknown data type $name"
}
