line
Note: The line utility is fully supported for compatibility with older UNIX systems.
However, it is recommended that the read utility be used instead because it
may provide greater functionality and is considered the standard for portable
UNIX applications as defined by POSIX.2 IEEE standard 1003.2-1992.
line copies one input line from its standard input (stdin) to its standard output
(stdout). The end of the line is the first newline encountered. This is useful in shell
files that need small amounts of input (for example, responses to prompts).
echo “Enter name:\c”
NAME=`line`
line uses the following localization environment variables:
v LANG
v LC_ALL
v LC_MESSAGES
v NLSPATH
See Appendix F for more information.
