新建的脚本，指定APP打开文件
#!/bin/sh
printHelpDoc()
{
printf "Usage: ./OpenFile.sh [-a <application>] [filenames] [--args arguments]\n"
printf "Help: Open opens files from a shell.\n\tBy default, opens each file using the default application for that file. \n\tIf the file is in the form of a URL, the file will be opened as a URL.\n"
printf "Options:\n"
printf "\t-a Opens with the specified application.\n\n\n"
}
#params count
paramCount=$#
printf "paramCount=$paramCount\n"
#是否包含第1个参数
if [ -z "$1" ]; then
printf "Please enter the valid arguments\n"
#printHelpDoc
exit 1
elif test $1 = "-a"
then
if [ -z "$2" ]; then
printf "Please enter the valid arguments\n"
exit 1
fi
fi
for (( i = 1; i <= paramCount; i++ )); do
#statements
params[i-1]="${!i}"
echo ${params[i-1]}
done
firstArg="${params[0]}"
secondArg="${params[1]}"
index=0
if test $firstArg = "-a" ; then
let index=2
fi
if [ $index -eq $paramCount ]; then
printf "open $firstArg $secondArg\n"
open "$firstArg" "$secondArg"
else
for (( i = index; i < paramCount; i++ )); do
#statements
arg="${params[i]}"
if test $firstArg = "-a" ; then
printf "$i open $firstArg $secondArg $arg\n"
open "$firstArg" "$secondArg" "$arg"
else
open "$arg"
fi
done
fi
执行过程中，发现带空格的参数总是不对，后来在脚本中取参数时都加上""，问题解决
