本文介绍Shell脚本中的一些实用技巧，包括如何编写清晰的用法说明、获取文件后缀、字符串替换、循环处理任务以及处理交互式命令。通过具体示例展示了如何优化脚本结构，提高脚本的可读性和效率。

1 用法，在我们编写的软件为了让用户使用你的软件，就有一个usage,例如

usage()
{
    ECHO "Usage: create-lsb-image ARCH ROOTFS_IMAGE"
    ECHO "ARCH : x86 or x86-64 or ppc32"
    ECHO "ROOTFS_IMAGE: Name of the rootfs image with suffix /"rootfs.tar.bz2/", i.e."
    ECHO "              poky-image-lsb-qemux86-20110317030443.rootfs.tar.bz2"

    ECHO ""
    ECHO "Examples:"
    ECHO "        creat-lsb-image x86 poky-image-lsb-qemux86-20110317030443.rootfs.tar.bz2"
}

-参数要用抽象的变量来代替

-然后解释每个变量

-增加一个具体的用法

2 如何得到文件明的后缀

suffix=${PACKAGE_NAME##*.}

3 替代

arch=${qemux86_64/x86_64/x86-64}

4 如果是重复的工作要用一个循环

这是一个不好的方式，下载每个包都要加好些语句

if [ -d lsb-test-suite-${MACHINE_ARCH} ];then
    cd lsb-test-suite-${MACHINE_ARCH}
    ECHO "Download lsb test suite, it could take some time..."
    wget -c -t 5 http://ftp.linuxfoundation.org/pub/lsb/bundles/released-4.1.0/dist-testkit/lsb-dist-testkit-4.1.0-5.${T_ARCH}.tar.gz
    exit_check
    ECHO "Download lsb-xdg-utils-4.0.0-2.${P_ARCH}.rpm"
    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/lsbdev/released-4.1.0/binary/${T_ARCH}/lsb-xdg-utils-4.0.0-2.${P_ARCH}.rpm
    exit_check
    ECHO "Downlocad lsb-apache-2.2.8-2.lsb4.${P_ARCH}.rpm"
    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/app-battery/released-4.1.0/${T_ARCH}/lsb-apache-2.2.14-3.lsb4.${P_ARCH}.rpm
    exit_check

    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/app-battery/released-4.1.0/${T_ARCH}/lsb-tcl-8.5.7-6.lsb4.${P_ARCH}.rpm
    exit_check
    ECHO "Downlocad lsb-expect-5.43.0-7.lsb4.${P_ARCH}.rpm"
    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/app-battery/released-4.1.0/${T_ARCH}/lsb-expect-5.43.0-11.lsb4.${P_ARCH}.rpm
    exit_check
    ECHO "Downlocad lsb-groff-1.19.2-4.lsb4.${P_ARCH}.rpm"
    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/app-battery/released-4.1.0/${T_ARCH}/lsb-groff-1.20.1-5.lsb4.${P_ARCH}.rpm
    exit_check
    ECHO "Downlocad lsb-raptor-1.4.16-2.lsb4.${P_ARCH}.rpm"
    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/app-battery/released-4.1.0/${T_ARCH}/lsb-raptor-1.4.19-3.lsb4.${P_ARCH}.rpm
    exit_check
    ECHO "Downlocad lsb-xpdf-1.01-7.lsb4.${P_ARCH}.rpm"
    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/app-battery/released-4.1.0/${T_ARCH}/lsb-xpdf-1.01-10.lsb4.${P_ARCH}.rpm
    exit_check
    ECHO "Downlocad lsb-samba-3.0.28a-3.lsb4.${P_ARCH}.rpm"
    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/app-battery/released-4.1.0/${T_ARCH}/lsb-samba-3.4.3-5.lsb4.${P_ARCH}.rpm
    exit_check
    ECHO "Downlocad lsb-rsync-3.0.0-2.lsb4.${P_ARCH}.rpm"
    wget -c -t 5 http://ftp.linux-foundation.org/pub/lsb/app-battery/released-4.1.0/${T_ARCH}/lsb-rsync-3.0.6-3.lsb4.${P_ARCH}.rpm
    exit_check
else
    ECHO "Can't find lsb test suite for ${MACHINE_ARCH}"
fi
好的方式，应该这样

if [ "${ARCH}" == "x86-64" ]; then
    COM_PACKAGE_LIST="lsb-dist-testkit-4.1.0-5.${P_ARCH}.tar.gz"
else
    COM_PACKAGE_LIST="lsb-dist-testkit-4.1.0-5.${T_ARCH}.tar.gz"
fi

APP_PACKAGE_RPMLIST="lsb-apache-2.2.14-3.lsb4.${P_ARCH}.rpm
                     lsb-tcl-8.5.7-6.lsb4.${P_ARCH}.rpm
                     lsb-expect-5.43.0-11.lsb4.${P_ARCH}.rpm
                     lsb-groff-1.20.1-5.lsb4.${P_ARCH}.rpm
                     lsb-raptor-1.4.19-3.lsb4.${P_ARCH}.rpm
                     lsb-xpdf-1.01-10.lsb4.${P_ARCH}.rpm
                     lsb-samba-3.4.3-5.lsb4.${P_ARCH}.rpm
                     lsb-rsync-3.0.6-3.lsb4.${P_ARCH}.rpm"

APP_PACKAGE_SOURCELIST="expect-tests.tar /
                        tcl-tests.tar /
                        raptor-tests.tar /
                        test1.pdf /
                        test2.pdf"

PACKAGE_LIST="${COM_PACKAGE_LIST} ${APP_PACKAGE_RPMLIST} ${APP_PACKAGE_SOURCELIST}"
RELEASE=released-4.1.0 #Version for lSB TEST SUITE
WGET="wget -c -t 5" # Tools of download packages

{

    for i in $@; do
        ECHO " -->Downloading package /"${i}/""
        PACKAGE_NAME=${i}
        suffix=${PACKAGE_NAME##*.}
        if [ $suffix = "gz" ];then
            ${WGET} ${SERVER1}/${i}
        elif [ $suffix = "rpm" ];then
            ${WGET} ${SERVER2}/${i}
        else
            ${WGET} ${SERVER3}/${i}
        fi
    done
}

if [ -d lsb-test-suite-${MACHINE_ARCH} ];then
    cd lsb-test-suite-${MACHINE_ARCH}
    ECHO "Downloading lsb test suite, it could take some time..."
    download ${PACKAGE_LIST}
else
    ECHO "Can't find lsb test suite for ${MACHINE_ARCH}"
fi
5 如何处理交互

在自动脚本中，类似mkfs.ext3 在运行的时候需要用户输入（yes/no）,如果我们的答案是肯定的。可用如下的方法

mkfs.ext3 poky-image-lsb-${MACHINE_ARCH}-test.ext3 > /dev/null 2>&1 <<End-Of-Session
y
End-Of-Session

6 > /dev/null/ 2>&1

将输出映射到/dev/null,将错误映射到输出。
