How to find command location in Linux?
How to find command location in Linux and Unix This is a small how to on finding your command location. Some times it’s required to find command location to use it as path is not set properly to /bin or /sbin or some other folder. And some times we install packages through scripts where the commands will be installed in a defined path other than /usr/bin or /usr/sbin etc. command to check where the particular command is installed? which command-name Example: which ls Output: root@surendra:/home/surendra# which ls /bin/ls root@surendra:/home/surendra# How about getting with other command along with manual pages? whereis command-name Example: whereis ls Output: root@surendra:/home/surendra# whereis ls ls: /bin/ls /usr/share/man/man1/ls.1.gz root@surendra:/home/surendra# some times we don’t know where the command is located but still we want to use it, at these times you can use which command to give entire path `which ls` or $(which ls) the above two are very much handy when writing shell scripts when you are not aware/sure where the command located. Please share your thoughts on how you avoid this situation....
