| + | ====== How to Reset the Command Path in Bash ====== | ||
| + | Occasionally when using bash after installing or updating packages, you may run into a problem like the following when trying to invoke a command: | ||
| + | |||
| + | < | ||
| + | #nano example.txt | ||
| + | -bash: / | ||
| + | directory | ||
| + | </ | ||
| + | |||
| + | In this case, after verifying the location of nano through which or whois, and checking your $PATH, you show the path is correct and the command is installed correctly. | ||
| + | |||
| + | < | ||
| + | # which nano | ||
| + | / | ||
| + | </ | ||
| + | |||
| + | < | ||
| + | # whereis nano | ||
| + | nano: / | ||
| + | </ | ||
| + | |||
| + | < | ||
| + | # echo $PATH | ||
| + | / | ||
| + | </ | ||
| + | |||
| + | Once you've confirmed that it should be working, the problem can be fixed in one of two ways. | ||
| + | |||
| + | **1.** Start a new bash session by terminating your current one. | ||
| + | |||
| + | **2.** Run the following command: | ||
| + | |||
| + | < | ||
| + | hash -r | ||
| + | </ | ||
| + | |||
| + | The **hash** command is a bash built-in to reload bash. | ||
