Set path under Linux

1. Direct with export command:

#export path= $PATH: Custom Path
To see if it is already set up, use the command export to view:

2, modify the profile file:
#vi/etc/profile
Add in:
Export Path= "$PATH: Custom Path"

3. Modify the. bashrc file:
# VI/ROOT/.BASHRC
Add in:
Export Path= "$PATH: Custom Path"
This method is used by the Zhangrong worm in use here. If you need to set the global path, you can modify/ETC/BASH.BASHRC, add the Export path= "$PATH: Custom Path" on it.

The latter two methods generally require a re-logoff system to take effect, and finally can be tested by the echo command:
# echo $PATH
See if the output already has a "custom path". The "$PATH" indicates that the previously set path is still valid, and be careful not to omit $.
