UNIX for Advanced & Expert Users

I have a huge file with record length around 5000 characters.
There is an ETL tool datastage which is writing this data to the file(AIX server). At position 4095 i have seen NULL Character(^@).

when i am using this command "head -1 file_nm | sed 's/\000//g'" --- the output is displaying prperly its removing NULL character but if i write this to another file its adding again.

head -1 file_nm | sed 's/\000//g' ----- Displaying Output without NULL
head -1 file_nm | sed 's/\000//g' > File_nm1 --- can see the NULL charcter in File_nm1.

I think by default AIX is inserting this NULL character for a file whose record length is huge... Is this true??

Please help me out

Code:

tr -d '\000' < file1 > file2

I have tried with "tr" already its the same issue

can you post the ouput of the below command

Code:

 
head -1 file_nm | od -c
