linux 下set指令

linux shell set 参数说明

背景我们经常见到很多设立了脚本 打头会写如下set -e或者set -ex或者set -eux这是什么意思呢？

具体解释一下Linux set命令用于设置shell。set指令能设置所使用shell的执行方式，可依照不同的需求来做设置。set所有的参数说明

set: set [-abefhkmnptuvxBCHP] [-o option-name] [--] [arg ...] Set or unset values of shell options and positional parameters. Change the value of shell attributes and positional parameters, or display the names and values of shell variables. Options: -a Mark variables which are modified or created for export. -b Notify of job termination immediately. -e Exit immediately if a command exits with a non-zero status. -f Disable file name generation (globbing). -h Remember the location of commands as they are looked up. -k All assignment arguments are placed in the environment for a command, not just those that precede the command name. -m Job control is enabled. -n Read commands but do not execute them. -o option-name Set the variable corresponding to option-name: allexport same as -a braceexpand same as -B emacs use an emacs-style line editing interface errexit same as -e errtrace same as -E functrace same as -T hashall same as -h histexpand same as -H history enable command history ignoreeof the shell will not exit upon reading EOF interactive-comments allow comments to appear in interactive commands keyword same as -k monitor same as -m noclobber same as -C noexec same as -n noglob same as -f nolog currently accepted but ignored notify same as -b nounset same as -u onecmd same as -t physical same as -P pipefail the return value of a pipeline is the status of the last command to exit with a non-zero status, or zero if no command exited with a non-zero status posix change the behavior of bash where the default operation differs from the Posix standard to match the standard privileged same as -p verbose same as -v vi use a vi-style line editing interface xtrace same as -x -p Turned on whenever the real and effective user ids do not match. Disables processing of the $ENV file and importing of shell functions. Turning this option off causes the effective uid and gid to be set to the real uid and gid. -t Exit after reading and executing one command. -u Treat unset variables as an error when substituting. -v Print shell input lines as they are read. -x Print commands and their arguments as they are executed. -B the shell will perform brace expansion -C If set, disallow existing regular files to be overwritten by redirection of output. -E If set, the ERR trap is inherited by shell functions. -H Enable ! style history substitution. This flag is on by default when the shell is interactive. -P If set, do not follow symbolic links when executing commands such as cd which change the current directory. -T If set, the DEBUG trap is inherited by shell functions. -- Assign any remaining arguments to the positional parameters. If there are no remaining arguments, the positional parameters are unset. - Assign any remaining arguments to the positional parameters. The -x and -v options are turned off. Using rather than - causes these flags to be turned off. The flags can also be used upon invocation of the shell. The current set of flags may be found in $-. The remaining n ARGs are positional parameters and are assigned, in order, to $1, $2, .. $n. If no ARGs are given, all shell variables are printed. Exit Status: Returns success unless an invalid option is given.

set -eux 也就是 以调试的方式执行shell ，只识别定义过的变量，同时脚本传回值非0 直接结束shell
