Dynamic command

[nitalc]

My file.txt contains following:

>> file.txt <<

line one goes here
line two is here
and so on.......

i want to replace the text in the file "one" with "hundred" using a shell script. My shell script contains the following command:

>> replaceText.sh<<

sed -i 's/one/$1/g' file.txt

I am calling it using:

./replaceText hundred

Instead of replacing "one" with "hundered" the shell script replaces it with $1.

How can I get this working?

>> replaceText.sh<<

sed -i 's/one/$1/g' file.txt

Change your single quotes (') for double quotes (") to make:

>> replaceText.sh<<

sed -i "s/one/$1/g" file.txt

Bash will not change any text within single quotes (e.g. expanding $1 into the first argument), but it will expand text in double quotes.

That worked . Thanks
