如何确定脚本本身中的Bash脚本文件的名称?
就像如果我的脚本在文件runme.sh中，那么我如何让它显示“您正在运行runme.sh”消息而不硬编码?
当前回答
使用bash >= 3，以下工作:
$ ./s
0 is: ./s
BASH_SOURCE is: ./s
$ . ./s
0 is: bash
BASH_SOURCE is: ./s
$ cat s
#!/bin/bash
printf '$0 is: %s\n$BASH_SOURCE is: %s\n' "$0" "$BASH_SOURCE"
其他回答
回显“您正在运行$0”
像这样的东西?
export LC_ALL=en_US.UTF-8
#!/bin/bash
#!/bin/sh
#----------------------------------------------------------------------
start_trash(){
ver="htrash.sh v0.0.4"
$TRASH_DIR # url to trash $MY_USER
$TRASH_SIZE # Show Trash Folder Size
echo "Would you like to empty Trash [y/n]?"
read ans
if [ $ans = y -o $ans = Y -o $ans = yes -o $ans = Yes -o $ans = YES ]
then
echo "'yes'"
cd $TRASH_DIR && $EMPTY_TRASH
fi
if [ $ans = n -o $ans = N -o $ans = no -o $ans = No -o $ans = NO ]
then
echo "'no'"
fi
return $TRUE
}
#-----------------------------------------------------------------------
start_help(){
echo "HELP COMMANDS-----------------------------"
echo "htest www open a homepage "
echo "htest trash empty trash "
return $TRUE
} #end Help
#-----------------------------------------------#
homepage=""
return $TRUE
} #end cpdebtemp
# -Case start
# if no command line arg given
# set val to Unknown
if [ -z $1 ]
then
val="*** Unknown ***"
elif [ -n $1 ]
then
# otherwise make first arg as val
val=$1
fi
# use case statement to make decision for rental
case $val in
"trash") start_trash ;;
"help") start_help ;;
"www") firefox $homepage ;;
*) echo "Sorry, I can not get a $val for you!";;
esac
# Case stop
由于一些注释询问没有扩展名的文件名，这里有一个示例如何完成:
FileName=${0##*/}
FileNameWithoutExtension=${FileName%.*}
享受吧!
$0将给出您正在运行的脚本的名称。创建一个脚本文件并添加以下代码
#!/bin/bash
echo "Name of the file is $0"
然后像这样从终端运行
./file_name.sh
使用bash >= 3，以下工作:
$ ./s
0 is: ./s
BASH_SOURCE is: ./s
$ . ./s
0 is: bash
BASH_SOURCE is: ./s
$ cat s
#!/bin/bash
printf '$0 is: %s\n$BASH_SOURCE is: %s\n' "$0" "$BASH_SOURCE"
