r — Process a command history list
Format
Description
r [old=new] [specifier]
Related Information
fc, history, sh
r is an alias for fc –s. Like fc –s, r reenters exactly one command without going
through an editor. If a command specifier is given, r selects the command to
reenter; otherwise, r uses the last command entered. To perform a simple
substitution on the command before reentry, use a parameter of the form old=new.
The string new replaces the first occurence of string old. r displays the (possibly
modified) command before reentering it.
See “fc — Process a command history list” on page 272 for more information.
read — Read a line from standard input
Format
Description
read [–prs] [–u[d]] [variable?prompt ] [variable ...]
When you call read without options, it reads one line from the standard input,
breaks the line into fields, and assigns the fields to each variable in order.
To determine where to break the line into fields, read uses the built-in variable IFS
(which stands for internal field separator). Encountering any of the characters in IFS
means the end of one field and the beginning of the next. The default value of IFS
is blank, tab, and newline.
