Hi all,
I have a shell script which is called with an arbitrary=20
message argument. Punctuation excludes * ? & | > < chars.
It processes it via an AWK command line 'script' and dumps the=20
result in a file for the SMS sender...
Nice and simple.
Except that the AWK script seems to duplicate the last character or two
in the message. Everything else in the 200 odd lines of shell scripts
surrounding this function run just fine, and this bit runs too,=20
but this tiny thing is _VERY_ annoying.
The shell code is listed below.
Please teach me what bit I missed .... (C and TCL are my forte, not AWK)
cheers
