Top Forums UNIX for Dummies Questions & Answers Ksh How to test if variable is numeric?? Post 302183651 by era on Wednesday 9th of April 2008 03:05:45 PM

Code:
case $zipcode in [0-9][0-9][0-9][0-9][0-9]) ;;
    *) echo "$myline"; echo "zipcode warning: $zipcode" >&2;;
esac

If it's five digits then it can't be bigger than 99999 or less than 00000, so that check seems superfluous. Also you seem to have a logic error there (it cannot be less than one and bigger than 99999). The check for bigger than 0 still needs to be done but it complicates things a bit so I didn't want to dilute this example with the handling of that.

how to set a variable to accept alpha-numeric characters?

I am working on a shell program that needs to accept alpha-numeric input (i.e., P00375); when I use a simple 'read' statement to read in the input (i.e., read LOG), I receive the message "p00375: bad number". How must I adjust my input statement to accept alpha-numerics? Thanks! Brent (3 Replies)

NAME
cfsndserv - crossfire client sound server DESCRIPTION
getzone adjusts and mixes sounds before playing them USAGE
getzone none - started automatically by crossfire client CONFIGURATION OPTIONS
~/.crossfire/sndconfig can contain the following options: stereo 1 means stereo sound, 0 - mono bits bitrate of generated sound - 8 or 16 signed if we should sent signed data to the soundcard. 1 means yes. frequency speed of playing data. This should be 11025, or sound pitch will change buffers how many buffers to allocate buflen how big the buffers should be. buffers*buflen shouldn't be smaller than the longest sound to be played. simultaneously home many sound can be played at the same time. When this setting is bigger, each sound volume will decrease. HOW DOES IT WORK
? The sound server gets information about sounds to be played on standard input. The information is a line: <sound number> <sound type> <relative x> <relative y> All those numbers are hex. The file ~/.crossfire/sounds contains description of sound numbers and types. For example: 3 0 5 0 Means that normal sound SOUND_FUMBLE spell should be played as it's source was5 units to the right of player. Sounds are mixed in special buffers, which are in fact one buffer, which should be big enough for the biggest sound to be played. The buffers, if contain anything, are sent one by one to the sound device. Each buffer is cleaned after playing. Sounds data is multiplied by some ratio (<1) evaluated from it's position and volume and added to the buffers, starting from the next after the one being played. So bigger buffer means bigger delay, before th sound is actually played, but the smaller buffer is, the bigger is possibility, we won't succeed filling the next buffer, before last is played.
