How to updatea file using a script

[bisla.yogender]

Hi All,

The scenerio is that I want to update some file using a scrript as example:

The file is:

>cat profile

Hi this is Yogender.
Yogender is here.
Is that really yogender ?
Ofcourse, he is Yogender.
Infact, he should be yogender.

Now i want to upadte "Yogender" in the file using a script where user can feed any name to replace "Yogender".

The script si as follow:

>sed_test
echo -en "enter your name:"
read name
echo "$name"

cat ~/aksutil/profile
cat ~/aksutil/profile|sed 's/Yogender/$name/g' profile|tee profile1

echo "Kindly check the file profile1"

But after executing ./sed_test withinput name "Hello". I am getting the following output stored in the new file profile1 created by the script.
>cat profile 1

Hi this is $name.
{$name} is here.
Is that really yogender ?
Ofcourse, he is $name.
Infact, he should be yogender.

However my expected output in Profile1 should be "Hello" instead of "$name".

Could any one please help me?


Thanks-
Yogender

Use ${name} in your sed:

cat ~/aksutil/profile|sed 's/Yogender/${name}/g' profile|tee profile1

Use ${name} in your sed:

cat ~/aksutil/profile|sed 's/Yogender/${name}/g' profile|tee profile1

This should not work.

Single quotes prevent the shell to expand variables, use double quotes instead and the use of cat is redundant.

Replace this line:

cat ~/aksutil/profile|sed 's/Yogender/$name/g' profile|tee profile1

with:

sed "s/Yogender/$name/g" ~/aksutil/profile | tee profile1
