NAME
read - read line of input into variables
Synopsis
read [OPTIONS] [VARIABLES...]
Description
The read builtin causes fish to read one line from standard input and
store the result in one or more environment variables.
o -c CMD or --command=CMD specifies that the initial string in the
interactive mode command buffer should be CMD.
o -e or --export specifies that the variables will be exported to
subshells.
o -g or --global specifies that the variables will be made global.
o -m NAME or --mode-name=NAME specifies that the name NAME should be
used to save/load the history file. If NAME is fish, the regular fish
history will be available.
o -p PROMPT_CMD or --prompt=PROMPT_CMD specifies that the output of the
shell command PROMPT_CMD should be used as the prompt for the
interactive mode prompt. The default prompt command is set_color
green; echo read; set_color normal; echo '> '.
o -s or --shell Use syntax highlighting, tab completions and command
termination suitable for entering shellscript code
o -u or --unexport causes the specified environment not to be exported
to child processes
o -U or --universal causes the specified environment variable to be
made universal. If this option is supplied, the variable will be
shared between all the current users fish instances on the current
computer, and will be preserved across restarts of the shell.
o -x or --export causes the specified environment variable to be
exported to child processes
Read starts by reading a single line of input from stdin, the line is
then tokenized using the IFS environment variable. Each variable
specified in VARIABLES is then assigned one tokenized string element.
If there are more tokens than variables, the complete remainder is
assigned to the last variable.
Example
echo hello|read foo
Will cause the variable $foo to be assigned the value hello.
