null char in text file

Jimmy_13 — Wed, 12 Mar 2003 02:12:44 GMT

I have a developer server whit hp-ux 11i.
The developers users ask me how they can insert a char null in the a text file.
They view the text file in hexadecimal format and search the 00 value that is the null char.
They need to now how write the null character in the text file, the null character is the 00 in hexadecimal

How i can write this char?

Hi,

I'm not at work so I can't test this, but I would try something like this:

echo "\000" >>text.file

Hi,

It depends on where you want to insert the null character. I use 'tr' to accomplish this. For ex., to replace End of Line with a null char , I would do the following

tr "\n" "\0" < your_file
