Shell Programming and Scripting

Hi,

I have a file with the path of the directory present somewhere in it.I have assigned the path of the directory name to a variable. I want to replace it with another string.The code i used was

sed -e '/$variable/sbcd/' filename.

since the path name includes slashes '/', my sed command is not working. How to solve this out to replace the path name with another string.

change the ' to " and use a different separator - not / plus you need an s:

Code:

sed -e "s#$variable#sbcd#" filename

Wow. Thats great. Thanks a lot.

Hi,

How do i replace one variable with another variable?

for e.g
inp1=ab
inp2=cd

how do i replace $inp1 with $inp2?

And how do i replace a string with a variable?

Can you please help?I am stuck here.

Can you please make the question more clear ?

What you like to do?
as i got your question it is a easy task to do

just do

Code:

$inp1=$inp2  or $inp2=$inp1

or elaborate more on the question part.

Buddy,

As my friend Dileep has correctly pointed out, your question seems to be confusing.
As per my understanding,
"how do i replace $inp1 with $inp2?" means u want to swap the values of the two variables, is it?
If yes then use one more variable and u can easily swap the values stored in the variables.
Replacing a string with a variable means you want to assign a variable to another variable rather then assigning it to some string,rite?
If so den u can do it d same way as u do for string. But here the variable needs to have some value stored in it.
