I wonder why they die not include that. If one wants it anyway, it is part of the GNU coreutils, which can be downloaded from <http://www.gnu.org/software/coreutils/>. After compiling, the sed binary can be copied to somewhere in the $PATH. > for i in {1..300}; do > ... > done This works for bash >= 3.2.

And i=`expr $1 + 1` can be i=$(( i + 1 )) or simply (( i++ )). The thread looks a little off-topic, but on the other hand a powerful tool like imagemagic can be made even more powerful with a little knowledge of shell scripting. In case someone got interested, I suggest the Advanced Bash Scripting Guide at <http://tldp.org/LDP/abs/html/>.
