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. windows-7), 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
${@#) does?$@is a special variable that holds all of the command line arguments? Well I've just used Bash string manipulation on that variable to remove the substring "-disableVenusBld", and then I compare it to the original$@. So if$@equals-foo -barthen${@#-disableVenusBld}would still be-foo -bar, so I can see that the flag I'm looking for isn't present. However, if$@equals-foo -disableVenusBld -barthen${@#-disableVenusBld}would be-foo -barwhich is not equal to$@, thus telling me that the flag I'm looking for is present! Cool eh!
