sh/Bash脚本静态分析和lint工具：ShellCheck。它不仅主要关注shell脚本典型初中级语法错误和shell输出的神秘的错误信息或者奇怪行为的缺陷,也能报告一些高级导致后来故障的高级问题。

What does ShellCheck check?

Here is an incomplete list of things ShellCheck warns about and suggests improvements to:

find . -name *.ogg

[[ n != 0 ]]

args="$@"

sed -e 's/foo/bar/g' file > file

[[ -e *.mpg ]]

grep '*foo*' file

PS1='\e[0;32m\$\e[0m '

find / -exec touch {} && echo {} \;

verbose='--verbose="true"' cmd $verbose

echo foo | read bar  echo $bar

time --format=%s sleep 10

rm "~/my file.txt"

for f in "*.ogg" do rm $f; done

echo $((n/180*100))

f() { rm file; }; sudo f

var=World; echo "Hello " var

for f in $(ls *.ogg) do ...; done

alias archive='mv $1 /backup'

files=(foo bar); echo "$files"

tar cf file$(date).tar dir

for $var in foo bar baz; do echo "$var"; done

touch $@

rm “file”

cmd 2>&1 > /dev/null

var$n="Hello"

echo ${var$n}

echo 'Path is $PATH'

[[ $n > 0 ]]

[ foo =~ re ]

PATH="$PATH:~/bin"

[[ $foo =~ "fo+" ]]

[[ -z $(find /tmp | grep mpg) ]]

[[ $foo==0 ]]

echo {1..$n}

while read host; do ssh "$host" uptime; done < file

echo $((3.14*r*r))

var=(1, 2, 3)

exec foo; echo "Done!"

touch ./-l; ls *

#!/bin/bash -x -e

printf "Hello $name"

[[ $1 -eq "shellcheck" ]]

var=42 echo $var

find . -name '*.bak' -o -name '*~' -delete

echo $(date)

cmd1 >> file; cmd2 >> file; cmd3 >> file;

sudo echo 'alias sl=ls' >> /etc/profile

tr '[a-z]' '[A-Z]'

trap "echo \"Runtime: ${SECONDS}s\"" exit

[ $n && $m ]

echo 'Don't forget to run foo --update!'

var='Don\'t try this at home'

ls *[:digit:].txt

printf "%s\n" "Command line was $@."

echo "Argument 10 is $10"

for d in *; do cd "$d"; cmd; cd ..; done

for f in *.mp3 do true; done

$foo=42

alias whereami="echo $PWD"

var = 42

#!/bin/sh echo {1..10}

cmd='echo foo'; `$cmd`;
