Retain the unmatched columns while joining
I have 2 files

Code:
file1
id  city    car type    model
1   york    subaru  impreza king
2   kampala toyota  corolla sissy
3   luzern  chrysler    gravity falcon

Code:
file2 
id  name    rating
3   zanzini PG
2   tara    X

when i use join sorted_file1 sorted_file2 >output i get something like this:

Code:
id  city    car type    model   name    rating
2   kampala toyota  corolla sissy   tara    X
3   luzern  chrysler    gravity falcon  zanzini PG

which is correct according to thecommand used. but i want to retain the unmatched line as well in output i,e.,'

Code:
ouput
id  city    car type    model   name    rating
1   york    subaru  impreza king
2   kampala toyota  corolla sissy   tara    X
3   luzern  chrysler    gravity falcon  zanzini PG

Try something like this:
Code:
#cat file1             
1   york    subaru  impreza king
2   kampala toyota  corolla sissy
3   luzern  chrysler    gravity falcon

Code:
#cat file2             
2   tara    X
3   zanzini PG

Code:
#join -a 1 file1 file2
1 york subaru impreza king
2 kampala toyota corolla sissy tara X
3 luzern chrysler gravity falcon zanzini PG

Code:

Code:
join -a 1 file1 file2 >output
