Apologies... Code that I shared earlier is incorrect, revising...

Revised Question:

First of all, I would like to apologize for the rush, I am new in QSHELL and just started learning.. But I badly need your help as I need to integrate the following to my program as soon as possible..

Basically the scenario is, a text file containing invalid/special characters was uploaded into our server and my program must remove them before processing.

so for example, I have uploadfile.txt and it contains below.

To replace the special characters I am using the following command and it works fine.

sed -e 's/[^a-zA-Z0-9&,-]/ /g' uploadfile.txt > outputfile.txt

1. a to z lowercase (a-z)
2. A to Z uppercase (A-Z)
3. 0-9
4. & Ampersand
5. , Comma
6. . Period

However, before replacing I need to extract the lines for reporting/communication purposes and I am not quite sure how and got stuck... Tried to search however I still cant get it and I am running out of time..

So my question is, How can I extract line numbers 2, 4, 5 into a separate text.file?

Thanks in advance.

This has been resolved, I used below command as suggested by @adminbee in the comments.

sed -n '/[^[:print:]]/p' IFS/MM4R5FLR/S06013/myfile.POL > myfile.pol
Thank you everyone for the help.

I am a noob programmer and trying to convert below GREP code to SED.

grep -ne '[a-zA-Z0-9&,-]p' 'myfile.txt' > 'myfile2.txt'

However I am not quite sure how since I am not familiar with qshell commands and just started studying. I badly need your help since I have to integrate the code to my program as soon as possible.

Basically what I am trying to do is - I want to extract lines that are not containing the following:

1. a to z lowercase (a-z)
2. A to Z uppercase (A-Z)
3. 0-9
4. Ampersand (&)
5. Comma (,)
6. Period (.)

Above grep file works however upon extracting myfile2.txt it contains unreadable/special characters. Tried below SED however it does not work.

sed -n '/[a-zA-Z0-9&,-]/' IFS/MM4R5FLR/S06013/LAWPOLaa.POL  

Thanks in advance.
