Bash在循环中检测错误，然后继续处理

我想处理包含在文本文件中的自制公式列表。如果存在安装错误（例如，已安装，错误的公式名称），我希望它写入错误，但继续处理。这个

到目前为止，我所拥有的：

...
# process list of formulas that have been installed
for i in $(cat $FILE) ; do

    echo "Installing $i ..."

    # attempt to install formula; if error write error, process next formula

    brew install $i

done
...

我该怎么做？

有帮助吗

...
# process list of formulas that have been installed
for i in $(< "$FILE") ; do

    echo "Installing $i ..."

    # attempt to install formula; if error write error, process next formula

    brew install "$i" || continue

done
...

这应该很简单

# process list of formulas that have been installed
for i in $(<"$FILE") ; do

    echo "Installing $i ..."

    # attempt to install formula; if error write error, process next formula

    if ! brew install $i
    then
        echo "Failed to install $i"
        continue
    fi

done

#已安装公式的处理列表
对于$中的i（当前脚本会发生什么情况？在brew命令后的下一行，添加以下内容：如果[$？-ne 0]；然后继续；fi或说brew某事| |继续。您应该查看“陷阱”命令。第二个选项尝试处理文件的空行。选择了第一个选项。我喜欢添加自定义错误消息的灵活性，但是
brew
的失败消息就足够了。
# process list of formulas that have been installed
for i in $(<"$FILE") ; do

    echo "Installing $i ..."

    # attempt to install formula; if error write error, process next formula

    if ! brew install $i
    then
        echo "Failed to install $i"
        continue
    fi

done
