在构建环境中,选择"Execute shell"或者"Execute shell script",这取决于你使用的Jenkins版本。 在脚本编辑框中,可以使用以下语法来引用环境变量: 在脚本编辑框中,可以使用以下语法来引用环境变量: 或者 或者 其中,VARIABLE_NAME是你定义的环境变量的名称。 如果你想在Bash脚本中设置环境变量,可以使用以下语法:
# 取消变量的值 unset my_variable 还可以使用环境变量为变量赋值。例如,可以使用$PATH环境变量: 代码语言:txt 复制 # 使用环境变量为变量赋值 current_path=$PATH echo "当前的PATH环境变量值为:$current_path" 参考链接: Bash变量赋值 相关搜索: linux bash 变量赋值 在bash中赋值位置变量 如何为bash中的布尔值...
declare 或 typeset 是一样的功能,就是在宣告变量的属性。如果使用 declare 后面并没有接任何参数, 那么 bash 就会主动的将所有的变量名称与内容通通叫出来,就好像使用 set 一样啦! 那么 declare 还有什么语法呢?看看先: [root@linux ~]#declare [-aixr] variable 参数: -a :将后面的 variable 定义成为数...
For example, the following will match a line (stored in the shell variable line) if there is a sequence of characters anywhere in the value consisting of any number, including zero, of characters in the space character class, zero or one instances of‘a’, then a ‘b’: [[ $line =~...

# The script is:str="welcome to the world"echo${str:0:10}echo${str:(-9)}# The result is:welcome to the world 5. 连接字符串 将两个或多个字符串添加或连接在一起,这称为字符串连接。bash中字符串连接的格式为: # 方法1:str3="$str1$str2"# 此命令将串联str1和str2变量的值,并将其存...
Setting the value when a variable isn't set You can make a variable default back to a certain string when a variable isn't set like so: ${variable:-string} Take this example: echo "Hello ${name:-nobody}!" Since the variablenameis not set, it will be defaulted tonobodyand the com...
read variable would take whatever input the user entered and store it in $variable. We then access this with echo and set up a neat sentence. This script is reasonably messy though; read has another function that could halve the size of this script. clear read -p "Please enter your ...

Here, I used theread commandto transfer the control from running script to the user, so that the user can enter a name and then store whatever user entered, in the 'name' variable. Finally, the script greets the user with their name: ...
