I don't know what command should I use in unix.
Let say I have a file like this:
A 23 B 52 C 36 F 25
and second file with 3 columns:
A aligator 2 B panda 3 C bear 4 D pig 1 E yeti 0 F shark 9 G dog 10 H cat 1
Now I would like to replace first column values (in 1 file) using the second column values (2 file) if the values from the first columns match between files
example of output:
aligator 23 panda 52 bear 36 shark 25
Can anyone help me?
