Here's a transcript from my efforts to answer one of your questions: root@Lyrebird root]# chroot /tftpboot/ Lyrebird:~# busybox sh BusyBox v0.61.pre (2002.12.30-09:30+0000) Built-in shell (ash) Enter 'help' for a list of built-in commands. # NUMDISKS=0 # ((++NUMDISKS)) ++NUMDISKS: No such file or directory # $((++NUMDISKS)) syntax error: "++NUMDISKS" # $((NUMDISKS++)) syntax error: "NUMDISKS++" # NUMDISKS=$((NUMDISKS++)) syntax error: "NUMDISKS++" # NUMDISKS=$((NUMDISKS+1)) syntax error: "NUMDISKS+1" # NUMDISKS=$(($NUMDISKS+1)) # echo $NUMDISKS 1 # -- Please, reply only to the list.
