Do your lines have a fixed length ?  
if yes you can use

```nohighlight
cut -c ...

```

otherwise

```nohighlight
read a
b=${a#*//*/*/*/*/} 
echo ${b%/*}/

```

```nohighlight
# a="BC://abcd.01/ABCDE/ABC.Monitor/tags/Release_0.39.16.200/db/ABC/02-DML.sql"
# echo $a
BC://abcd.01/ABCDE/ABC.Monitor/tags/Release_0.39.16.200/db/ABC/02-DML.sql
# b=${a#*//*/*/*/*/}
# echo ${b%/*}/
Release_0.39.16.200/db/ABC/

```

Is it this you are looking for?

```nohighlight
$ awk -F/ '{print $7,$8,$9FS}' OFS=/ file
Release_0.39.16.200/db/ABC/
Release_0.39.16.200/db/ABC/

```

</div>

Or if you need the trailing / you can do it with awk also :

```nohighlight
awk -F/ '{print $7,$8,$9,x}' OFS=/ infile
Release_0.39.16.200/db/ABC/
Release_0.39.16.200/db/ABC/

```

use `cut` directly.

```nohighlight
cut -d \/ -f7- < infile

```

almost ... you need to get rid off the trailing [^/]\*.sql chain
