for var do : do something with $var done

Or:

do : do something with $var done

man bash:

Compound Commands ... for name in word ; do list ; done The list of words following in is expanded, generating a list of items. The variable name is set to each element of this list in turn, and list is executed each time. If the in word is omit- ted, the for command executes list once for each positional parameter that is set (see PARAMETERS below). The return status is the exit status of the last command that executes. If the expansion of the items following in results in an empty list, no commands are executed, and the return status is 0. ... Special Parameters The shell treats several parameters specially. These parameters may only be referenced; buttignment to them is not allowed. * Expands to the positional parameters, starting from one. When the expansion occurs within double quotes, it expands to a sin- gle word with the value of each parameter separated by the first character of the IFS special variable. That is, "$*" is equiva- lent to "$1c$2c...", where c is the first character of the value of the IFS variable. If IFS is unset, the parameters are sepa- rated by spaces. If IFS is null, the parameters are joined without intervening separators. the expansion occurs within double quotes, each parameter expand to nothing (i.e., they are removed).
