Question

I need to launch something, to verify a file.
A text separated in two fields by a comma,
on the second field we may find /*/*/* which is data I want.
I want to discard /*/* only

Input file

\\CIFSERVER1\Share1,/fs1_casa/c/share1
\\CIFSERVER1\Share2,/fs2_casa/c/share2
\\CIFSERVER1\Share3,/fs1_casa/c/share3
\\EDULIN\edu,/edu1
\\CIFSERVER2\root,/fs1_casa
\\CIFSERVER2\root,/fs2_casa
\\CIFSERVER2\root,/fs3_casa
\\CIFSERVER2\root,/fs1_casa

Output should be:

\\CIFSERVER1\Share1,/fs1_casa/c/share1
\\CIFSERVER1\Share2,/fs2_casa/c/share2
\\CIFSERVER1\Share3,/fs1_casa/c/share3

What should be removed?

\\EDULIN\edu,/edu1
\\CIFSERVER2\root,/fs1_casa
\\CIFSERVER2\root,/fs2_casa
\\CIFSERVER2\root,/fs3_casa
\\CIFSERVER2\root,/fs1_casa

Answer 1

If you are trying to print all lines that contain more than 3 / after a single , you could just do:

sed -n '\@,.*/.*/.*/@p' input

To restrict to those lines containing exactly 3 /:

sed -n '\@,\([^/]*/\)\{3\}[^/]*$@p' input

If you must restrict the search to the second field (eg, there may be more than 1 comma):

awk '$2 ~ /[/].*[/].*[/]/' FS=, input

or

awk -F, '$2 ~ /\/.*\/.*\//'  input
