可以看见在当前文件夹下创建了一个icons文件夹

最后还压缩了文件夹

#!/bin/bash# readPlist [plist] [key]function readPlist() {    plist=$1    key=$2    value=`plutil -p "$plist" | grep $key | awk -F '=>' '{print $2}' | sed -e 's/\"//g'`    echo $value}# copyAppIcon [app] [dir]function copyAppIcon() {    apath=$1    iDir=$2    appName="${apath##*/}"    if [ -d "$apath" ]; then        icon=`readPlist "$apath/Contents/Info.plist" "CFBundleIconFile"`        if [ "${icon##*.}" != "icns" ]; then            icon="$icon".icns        fi        cp "$apath/Contents/Resources/$icon" "$iDir/$appName.icns"    fi}iconDir="icons"mkdir $iconDirmkdir $iconDir/Applicationsmkdir $iconDir/UtilitiesÅfor app in /Applications/*do    if [ "$app" != "/Applications/Utilities" ]; then        copyAppIcon "$app" $iconDir/Applications    fidonefor app in /Applications/Utilities/*do    copyAppIcon "$app" $iconDir/Utilitiesdoneecho "[*] copy icons done"zip -rq icons.zip $iconDir/*echo "[*] compresses the folder done"rm -r $iconDirecho "[*] del icons folder done"
