Bash脚本/函数

Question

我正在尝试设置bash函数，以便输入几个参数并创建一个git拉请求：

gpreq "<title>" "<ticketnumber>" "<release>" "<briefdescription>"

我尝试过这两种功能，但都没有用：

gpreq () {
    hub pull-request -m "$1\n\n Ticket: https://ticketsystem.net/issues/$2\n Target Release: $3\n Description: $4" ; }

而且还

gpreq() {
    STR="${1}"$'\n\n Ticket: https://ticketsystem.net/issues/'$"${2}"$'\n Target Release: '$"${3}"$'\n Description: '$"${4}"
    hub pull-request -m "${STR}" ;
}

由于某些原因，行间隔似乎不起作用，相反，\n是作为实际字符出现的。任何帮助都将不胜感激！

Answer 1

(我不知道什么是枢纽)

N是由将命令转换为换行符的字符。

尝试直接插入换行符

hub pull-request -m "$1

 Ticket: https://ticketsystem.net/issues/$2
 Target Release: $3
 Description: $4"

或者使用一些解释\n的函数：

STR="$1\n\n Ticket: https://ticketsystem.net/issues/$2\n Target Release: $3\n Description: $4"
STR
hub pull-request -m "`printf "${STR}"`"
