Shell Programming and Scripting

I was aware about the result.
But those are also the parent dir as you mentioned.

Do you have these fix set of dir? if yes then of course you can format the output. but if those are just the example then what is the rule behind printing of parent dir?

Try:

Code:

awk '$0~p"/"{print p}{p=$0}' infile

@anchal_khare: It's just an example. The rule is if there are a line /dir1/dir2 and other lines which the same as first line plus more "dir*" /dir1/dir2/dir3a, /dir1/dir2/dir3b or /dir1/dir2/dir3a/dir4... then only print /dir1/dir2

@Scrutinizer: If I add only one more line /Bicycle (mean it doesn't have sub dir) then it will not be printed out. Do you have another solution ? Thanks

Anyone help ?

Code:

sort file | awk '$0 !~ var || NR == 1 {  var=$0; print; } '

Thanks anbu23 ! It works well
