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
如果不带路径,可以使用${0##*/}
其他回答
如果你调用shell脚本喜欢
/home/mike/runme.sh
$0是全名
/home/mike/runme.sh
Basename $0将获得基本文件名
runme.sh
你需要把这个基本的名字放到一个变量里,比如
filename=$(basename $0)
并添加额外的文本
echo "You are running $filename"
你的脚本就像
/home/mike/runme.sh
#!/bin/bash
filename=$(basename $0)
echo "You are running $filename"
# ------------- SCRIPT ------------- #
#!/bin/bash
echo
echo "# arguments called with ----> ${@} "
echo "# \$1 ----------------------> $1 "
echo "# \$2 ----------------------> $2 "
echo "# path to me ---------------> ${0} "
echo "# parent path --------------> ${0%/*} "
echo "# my name ------------------> ${0##*/} "
echo
exit
# ------------- CALLED ------------- #
# Notice on the next line, the first argument is called within double,
# and single quotes, since it contains two words
$ /misc/shell_scripts/check_root/show_parms.sh "'hello there'" "'william'"
# ------------- RESULTS ------------- #
# arguments called with ---> 'hello there' 'william'
# $1 ----------------------> 'hello there'
# $2 ----------------------> 'william'
# path to me --------------> /misc/shell_scripts/check_root/show_parms.sh
# parent path -------------> /misc/shell_scripts/check_root
# my name -----------------> show_parms.sh
# ------------- END ------------- #
像这样的东西?
export LC_ALL=en_US.UTF-8
#!/bin/bash
#!/bin/sh
#----------------------------------------------------------------------
start_trash(){

感谢Bill Hernandez提供的信息。我增加了一些我正在采用的偏好。
#!/bin/bash
function Usage(){
echo " Usage: show_parameters [ arg1 ][ arg2 ]"
}
[[ ${#2} -eq 0 ]] && Usage || {
echo
echo "# arguments called with ----> ${@} "
echo "# \$1 -----------------------> $1 "
echo "# \$2 -----------------------> $2 "
echo "# path to me ---------------> ${0} " | sed "s/$USER/\$USER/g"
echo "# parent path --------------> ${0%/*} " | sed "s/$USER/\$USER/g"
echo "# my name ------------------> ${0##*/} "
echo
}
干杯
由于一些注释询问没有扩展名的文件名,这里有一个示例如何完成:
FileName=${0##*/}
FileNameWithoutExtension=${FileName%.*}
享受吧!
