The one in ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/shl112b.zip does expressions like 3>1 just fine. You simply have to note that the greater than sign (>) is a special character for the shell and need to be properly escaped. In COMMAND.COM: D:\TEMP> expr 3 ">" 1 1 D:\TEMP> expr 3 "<" 1 0 In bash: /temp $ expr 3 \> 1 1 /temp $ expr 3 \< 1 0 -- Weiqi Gao weiqigao AT a DOT crl DOT com
