Solve the problem of sed replacement text containing special characters such as "/" and "#"

If we use the sed command, if there are special characters, an error may be reported. The example is as follows:

# / cannot be used as a delimiter, because it will conflict with the content insidesed -i 's/flink//etc/g'# pound sign# cannot be used as a delimiter, because it will conflict with the content insidesed -i 's#jdbc://127.0.0.1&password=1#aa$username=root#g'# @ cannot be used as a delimiter, because it will conflict with the content insidesed -i '[email protected]://[email protected][email protected]'

How to solve it?

We have to look inside to choose a specific delimiter, for example:

• It contains "/", you can choose "#" or "@" as a delimiter;
• It contains "#", you can choose "@" or "/" as the delimiter;
• contains "@", you can choose "/" or "#" as the delimiter.

So what if all of the above were included?The escape character "\" can only be used in the replaced text, such as:

sed -i 's/oracle/\/etc\/oracle/g'
