How to use sed?

[lin.chen]

Would you please help me to resolve this problem.

I would like to replace 'wnctce' to 'xxstitst' in file, and how could i do?

sed -e ‘s/\’wnctce\’ /\’xxstitst\’/g’< /plmap/SCRIPTS/DATA/0209/wncplm_dump0209.txt > xxstitst_dump0209.txt

this command is wrong.. How could i correct it?

thanks!!

sed -e 's/\'wnctce\'/\'xxstitst\'/g'< /wncplm_dump0209.txt > xxstitst_dump0209.txt

Hi Lin:

Change the delimiters that bound the 'sed' program to make them differ from part of what you want to match.

Instead of:

# echo \'wnctce\'|sed -e 's/\'wnctce\'/\'xxstitst\'/g'

Use:

# echo \'wnctce\'|sed -e "s/\'wnctce\'/\'xxstitst\'/g"

...which would output:

'xxstitst'

Regards!

Hi lin chen

do it like this :

sed -e "s/'wnctce'/'xxstitst'/g" < /wncplm_dump0209.txt > xxstitst_dump0209.txt

you will have less trouble with quote and escapes characteres

Hope this will help

Regards

You might want to mention that you also want to change those single quotes and they weren't just meta characters in your question.
