Hi all,
I need to replace a line
export TZ=xxxxxxxx
with the line
export TZ=$1
Now, "xxxxxxxx" in the above line is some unknown string and $1 is a parameter. I want the content of $1 to be replaced with "xxxxxxxx".
Kindly help me how to do this in the shell scripting.
sed -i "s/export TZ=xxxxxxxx/export TZ=$1/" file
I think the following line could help you

Hi Balajesuri,
The "xxxxxxxx" is an unknown string. It could be "abcd" or "xyz" etc. I mentioned "xxxxxx" to indicate unknown string. So I can't search for this string.
Now, say $1= "mnopqr".
If I say "export TZ=$1" in the field for line to be replaced with in the sed command, will it write "export TZ=$1" or "export TZ=mnopqr".
I'd want it to be replaced with "mnopqr" and not $1.
sed -i "s/export TZ=[^ ]*/export TZ=$1/" file
Hi Balajesuri,
This works well. Thanks
