sed does not remove word done from within shell script


I am trying to create a script to remove all instances of the word done from within my script. then cat a text file with the word done in it to append the word done at the end of my script so the while loop terminates properly


sed -i "s/done/ /g" /home/dnoob/script

cat text >> /home/dnoob/script

this does append the word done however
after i run the script the sed commands removes
the word done from within the sed command only

sed -i "s/ / /g"

what is wrong with my syntax here

I have tried single qoutes and back slash

From within what sed command? Is there one in the file?

You may need to explain further.

Hi,

is the 'sed' command inside your script that you want to modify??
Please post your script.
Another issue: You do not need to cat the word done from another text file. You can do this with sed:
Code:
sed -i 's/done/ /g;$ a done' /path/to/file
