rm指令：删除文件或目录
首先 man rm
NAME
rm - remove files or directories
SYNOPSIS
rm [OPTION]... FILE...
DESCRIPTION
This manual page documents the GNU version of rm. rm removes each specified file. By default, it does not remove directories.
If a file is unwritable, the standard input is a tty, and the -f or --force option is not given, rm prompts the user for whether to
remove the file. If the response is not affirmative, the file is skipped.
OPTIONS
Remove (unlink) the FILE(s).
-f, --force
ignore nonexistent files, never prompt
-i, --interactive
prompt before any removal
--no-preserve-root do not treat ‘/’ specially (the default)
--preserve-root
fail to operate recursively on ‘/’
-r, -R, --recursive
remove directories and their contents recursively
-v, --verbose
explain what is being done
--help display this help and exit
--version
output version information and exit
By default, rm does not remove directories. Use the --recursive (-r or -R) option to remove each listed directory, too, along with
all of its contents.
To remove a file whose name starts with a ‘-’, for example ‘-foo’, use one of these commands:
rm -- -foo
rm ./-foo
rm -rf jaxb-xjc.jar
rm -rfv jboss-aop-asintegration-core.jar
已删除“jboss-aop-asintegration-core.ja
rm -rfvi jboss-aop-asintegration-jmx.jar
rm：是否删除 一般文件 “jboss-aop-asintegration-jmx.jar”? y
已删除“jboss-aop-asintegration-jmx.jar”
rm -rfi jboss-aop-asintegration-mc.jar
