Your request is a bit difficult to understand. What be the CF char? What is "date"? For the others, you don't need a script but can use e.g. grep with a regex like
grep [^[:alnum]&] client.txt is incorrect for various reasons.
You are missing a colon at the end of alnum, before ]; to make it an alphanumeric class set [:alnum:] Search some more for it if you want to know what that set would include.
The [^] means exclude the following
The & has to be escaped or protected, since it has special meaning for the shell
In English, it says to grep:
search in the file client.txt for any character that is not an alphanumeric or an ampersand.
Therefore it would show:
Code:
# single quotes to protect the & from the shell
grep '[^[:alnum:]&]' client.txt
pallvi mahajan # shows because there is a space
Sunny Sapen # same as above
F.K.S enterprise # it shows because periods and space
London & university # it shows because spaces
Banker's & Banker # it shows because spaces and (')
Kapil/ yadav # it shows because (/) and space
Let's add spaces into the exclusion class set
Code:
# there is a space inside the outer [] before &
grep '[^[:alnum:] &]' file
F.K.S enterprise # this shows now because the (.)
Banker's & Banker # this shows because (')
Kapil/ yadav #this shows because (/)
Let's exclude the (') from the list of wanted. Since (') has special meaning for the shell we have to change the quoting scheme that we use.
Code:
# \' and \& will do it
grep "[^[:alnum:] \'\&]"
F.K.S enterprise
Kapil/ yadav
I think this should be enough, now, to understand and figure out what you must do. Take another look at RudiC's initial exclusion class set.
