以下问题与this question上发布的答案有关:
我喜欢创建我自己的函数来打开一个新终端的概念,所以Craig Walker在上面引用的问题中链接到的脚本符合我的需求。由Mark Liyanage编写的脚本被发现here.
那个脚本是这样的:
#!/bin/sh
#
# Open a new Mac OS X terminal window with the command given
# as argument.
#
# - If there are no arguments, the new terminal window will
# be opened in the current directory, i.e. as if the command
# would be "cd `pwd`".
# - If the first argument is a directory, the new terminal will
# "cd" into that directory before executing the remaining
# arguments as command.
# - If there are arguments and the first one is not a directory,
# the new window will be opened in the current directory and
# then the arguments will be executed as command.
# - The optional, leading "-x" flag will cause the new terminal
# to be closed immediately after the executed command finishes.

if [ "x-x" = x"$1" ]; then
EXIT="; exit"; shift;
fi
if [[ -d "$1" ]]; then
WD=`cd "$1"; pwd`; shift;
else
WD="'`pwd`'";
fi
COMMAND="cd $WD; $@"
#echo "$COMMAND $EXIT"
osascript 2>/dev/null <<EOF
tell application "Terminal"
activate
do script with command "$COMMAND $EXIT"
end tell
EOF
我对链接网站上的脚本进行了一处更改;我注释掉输出“$ COMMAND $ EXIT”的行以消除一些冗长。但是,当我运行脚本时,我仍然得到此输出
tab 1 of window id 2835
就在它打开新窗口并执行我传入的命令之前。任何想法为什么会发生这种情况? (我尝试在调用oascript之前将stderr的重定向移动到/ dev / null,但这没有任何区别。)
答案 0 :(得分:8)
tab 1 of window 2835
是do script
命令返回的对象的AppleScript表示形式:它是为执行命令而创建的tab
实例。 osascript
将脚本执行的结果返回给标准输出。由于AppleScript脚本中没有明确的return
,因此整个脚本的返回值是最后执行的语句的结果,通常是do script
命令。两个最简单的修复方法是重定向osascript的stdout(如果出现错误,最好不重定向stderr):
osascript >/dev/null <<EOF
或在AppleScript中插入显式return
(没有值)。
tell application "Terminal"
activate
do script with command "$COMMAND $EXIT"
end tell
return
