Have been trying to develop a script that reads a string from an input file then looks up that string in a reference file to get a number, then inset that number back into the original file at a certain point (_____):
I tried rexx first but it was painfully slow probably because the lookup file is 167K lines long!
What is the fastest way to perform this kind of search in unix and can anyone give an example!
I want to pass arguments to a sh program and I want to use these arguments in the program as variables?
Will I use argc and argv in a main function can anyone around me write the full code please
for example when I write in th command
sh myprogram.sh argument1 argument2

Greetings. I have a RedHat 5.7 64bit virtual server on VMware ESXi 4.1. This server and other Redhat Servers are running very slow. I did some stats collection on ESXi and looks like Linux is holding the disk IO. I am not sure what is causing this behavior.

gpstrans
GPSTRANS(1) GPS Utility GPSTRANS(1)NAME
gpstrans - communicate with Garmin GPS receiver
SYNOPOSIS
gpstrans [ options ] [ file ]
DESCRIPTION
gpstrans allows the user with a Garmin GPS receiver to upload and download waypoints, routes, almanacs (satellite orbital elements) and
trackroutes. If file is not supplied, data will be read from stdin (-ux switch) or written to stdout (-dx switch).
OPTIONS -pport set serial I/O device
-s set datum, format, offset, and device interactively, and save them in $HOME/.gpstrans.
-i identify connected GPS
-o turn off GPS device
-t get time from GPS
-ts get time from GPS and set system time on host
-dx download data indicated by x: r=route, t=track, w=waypoint, a=almanac
-m With -dt, downloads track data in the format which can be displayed by Mayko mXmap(1). With -dr or -ur, downloads or uploads route
data in a format compatible with Mayko mXmap.
-ux upload data indicated by x: r=route, t=track, w=waypoint, a=almanac
-v print program version.
--verbose
Increase verbosity.
--debug
Add debug printouts.
--help Print help text.
CONNECTION
For a DB-25 connector, you may need to connect pin 4, 5 and 6, 8, 20 together. This sets handshake signals so that your workstation can use
the serial port to communicate with the GPS.
1 ### #####
o o o # # # o # o o o o o
o o o o o o # o o o o o
Connect the Garmin cable as follows:
2 3 7
o o o o o o o o o o o o o
o o o o o o o o o o o o
Pin 2 goes to DATA IN (White)
Pin 3 goes to DATA OUT (Brown)
Pin 7 goes to GROUND (Black)
If it doesn't work in this way, try exchanging pins 2 and 3 at the connector.
The circular connector on a Garmin GPS II receiver can be wired to a DB-9 connector as follows:
_____ _____,-----,
3 / 4 | | |
| o o | | | |_____
| < <- groove -> |=====| |----,|
| o o | | | | ||
2 _____ / 1 |_____| | ||
`-----' ||
||
views are looking ||
into connector ||
at each end of cable ||
||
||
5 3 2 ________ ||
o o o o o | \___________||
o o o o |_________,------------'
DB-9 pin 2 goes to circular connector pin 2
DB-9 pin 3 goes to circular connector pin 4
DB-9 pin 5 goes to circular connector pin 3
other pins are not connected
(Note: the pin numbers for the circular connector are
arbitrary, and may not match the `official' numbers.)
If your plug is more recent than the one above (ex: etrex) then you need DB-9 or DB-25 to be connected to your Garmin GPS like this:
_____,-----,
POWER(+) | | |
groove --> |=====| |_____
DATA IN | | |----,|
DATA OUT | | | ||
GROUND(-) |_____| | ||
`-----' ||
||
||
||
||
||
||
________ ||
| \___________||
|_________,------------'
DB-25 :
2 3 7
o o o o o o o o o o o o o
o o o o o o o o o o o o
Pin 2 goes to DATA IN (White) Pin 3 goes to DATA OUT (Brown) Pin 7 goes to GROUND (Black)
DB-9:
5 3 2
o o o o o
o o o o
pin 2 goes to DATA IN (White)
pin 3 goes to DATA OUT (Brown)
pin 5 goes to GROUND (Black)
other pins are not connected
For testing, you might try setting the GPS to NMEA-Output and using a terminal emulator program like Kermit. The GPS will send a data
record every 2 seconds. As long as you don't see any data on your computer, gpstrans won't work.
After finishing the test, be sure to set your GPS receiver to GRMN/GRMN.
ENVIRONMENT
GPSDEV Serial I/O device (overrides contents of $HOME/.gpstrans, and is overridden by -p switch).
FILES
$HOME/.gpstrans
Has user preferences for datum, format, offset, and serial I/O device (see -s switch, above).
