How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
lang-bash
var5="${var4/var1/$var1}"as well asecho "$var5".var5=${var5/var3/$var3}and if you want to keep the single quotes inmyfunction('var1','var2','var3'), you should definevar4usingvar4="myfunction('var1','var2','var3')". But I can't see a reason why the output should be jumbled.var3, butvar1twice. Second, yourvar4does not have any single quotes within it, but somehow the output has them anyway. Please post the exact script you use when asking for help online, the details matter.
