Hi

I want to remove "^O" from a file

I removed "^L" using the command
#/bin/sed "s/^L//g" /home/fil1

which command will remove ^O?

Hello.

Both sed and tr allow you to do this.

tr supports "\NNN" syntax to specify octal nubers.

sed understands "\cX" syntax to specify control characters (directly applicable to your scenario), as well as "\dXXX", "\oXXX" and "\xXX".

I recommend you read info pages for sed.

Goran

/bin/sed "s/^O//g" /home/file1 using this command it is not filtering "^O" (CtrlO)

Example of the file is given below please help me..

1^O^FH^SL1^R^24052010^1^D^PNEC002
2^BH^1^8^24Q^

Please read the documentation and make sure you understand it before repeating your question.

The solution is really trivial:

sed -e 's/\co//' ...
