If you're ok with integer math and no switches, you can easily make your own seq. The next time that you are on an OSF/1 operating system, you can use this portable version. It's also probably faster than the fork() overhead, assuming dash. seq () { if [ -n "$3" ] then FIRST=$(($1 + 0)) INCREMENT=$(($2 + 0)) LAST=$(($3 + 0)) else if [ -n "$2" ] then FIRST=$(($1 + 0)) INCREMENT=1 LAST=$(($2 + 0)) else FIRST=1 INCREMENT=1 LAST=$(($1 + 0)) fi fi c=$FIRST until [ $c -gt $LAST ] do printf %d\\n $c c=$((c + INCREMENT)) done }
