$! Substitutes the (decimal) process number of the last background process<br />

started by this shell.<br />

$< Substitutes a line from the standard input, with no further interpretation<br />

thereafter. It can be used to read from the keyboard in a shell script. While<br />

csh always quotes $ echo ^cr*<br />

bang ouch<br />

negated correctly.<br />

preserved: /usr/source/s1/{oldls,ls}.c expands to /usr/source/s1/oldls.c<br />
