有条件地执行命令.

语法

  if test-commands; then
    consequent-commands;
  [elif more-test-commands; then
    more-consequents;]
  [else alternate-consequents;]
  fi

或者在一行中:

 if test-commands; then consequent-commands; fi

例子


var=snark
[[ "$var" = "snark" ]] && echo "found snark"

#等效使用if:

var=snark
if [[ "$var" = "snark" ]]
 then echo "found snark"
fi

#测试文件 music.txt 是否存在:

If [[ -e music.txt ]]; then   
  echo "we found the file"
fi

if是一个bash内置命令
