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
alias?--backupto themvoptions, however that won't makeunrmwork twice in reverse.rmalias has a very strange path in it:../TrashCan/zarnihu. That's going into a TrashCan directory that is a sibling to your home directory. Additionally, theunrmalias right below uses the environment variable$TRASH_CAN. Can you tell us the result ofecho $TRASH_CANand alsocd ~; pwd; cd /u/y2010/zarnihu/../TrashCan/zarnihu; ls -al. I suspect that either your TrashCan directory is supposed to be under your home dir, or that the permissions are not set correctly in the TrashCan directory.
