Easy UNIX notation question

[lavaghman]

can anyone tell me what exactly the following UNIX notation code does cause I need to do the same in windows?

for x in webapps/sal/*.htm*
do
mv $x $x.bak
sed 's@bob@sal@g' $x.bak > $x
done



Thanks

This finds any htm files in the /webapps/sal directory and moves the x.htm file to x.bak, then sed parses the x.bak file for the name bob and replaces it with sal recursely. The file is then moved back to x.htm or the same as it was before. These files are processed one at a time.
