Exclude specific word from input file problem asking...
Hi,
Below is my input file and desired output file:
Input file:
Code:
>header_N_1
ASFDGDGNDGEGWETWRYWTETWNETOWETWETWNETTETNWET
.
.

Desired output file:
Code:
>header_N_1
ASFDGDGDGEGWETWRYWTETWETOWETWETWETTETWET
.
.

From the input file, I just hope to exclude the 'N' word from its content without effect the header content.
Thanks for any advice.

A sed solution for the case where a header may occur outside the first line of the file:
Code:
sed '/^>header/!s/N//g' file

Regards,
Alister
