Execute the Sed command… here is a solution to the problem.
Execute the Sed command
When I run the command
sed -e "s/$1/@root@The-Three-Little-Pigs-Siri-Proxy/" -i gen_certs.sh
I get the following error. I’m trying to replace the text $1 with another one below in the same file, instead of creating a new one, just modifying the current one.
sed: -e expression #1, char 0: no previous regular expression
Any ideas that could lead to errors and how to fix it?
Operating system: Ubuntu 10.10 32-bit
Solution
$1
If it is a double-quoted string, it will be expanded to an empty string (‘').
You can use single quotes to keep the literal value of $1
:
sed -e 's/$1/@root@The-Three-Little-Pigs-Siri-Proxy/' -i gen_certs.sh
