Getting current path in variable and using it
提问by R0b0tn1k
I would like to extract the current path in a variable and use it later on in the script
我想提取变量中的当前路径并稍后在脚本中使用它
Something like:
就像是：
myvar = pwd
Later on:
稍后的：
cd myvar
But my bash skills have rusted over the years.
但是这些年来我的 bash 技能已经生锈了。
How would i go on about doing that?
我将如何继续这样做？
采纳答案by digitalarbeiter
myvar="$PWD"
cd "$myvar"
(Quotes are necessary if your path contains whitespaces.)
（如果您的路径包含空格，则需要引号。）

Something like this should work:
这样的事情应该工作：
myvar=`pwd`
# ...
cd $myvar

in bash
在 bash
$ a=$(pwd)
回答by Joachim Sauer
Ind addition to the pwdcommand and the $PWDenvironment variable, I'd also suggest you look into pushd/popd:
除了pwd命令和$PWD环境变量之外，我还建议您查看pushd/ popd：
/$ pushd /usr /usr / /usr$ pushd /var/log /var/log /usr / /var/log$ popd /usr / /usr$ popd / /$

It worked for me:
它对我有用：
currentdir=$(cd -)
printf "Generating content at $currentdir\n"
