The -e option of sed is to input a valid sed expression, not a file name containing sed commands, the -f option is for filename containing valid sed expressions.
In your case:
sed -e sedscript.sh
is being treaded as a substitution (s) operation of sed as the expression starts with s, with e as the delimiter for s (substitution), and sed is rightly complaining about the unterminated s (substitution) command.
Have fun:
% sed -e sedscript.sheFOOe <<<'dscript.shBAR'
FOOBAR
What you can do:
Your file is necessarily a shell script, you can simple execute that as so
Use -e to put the expession on the command line directly, -e is not strictly needed though:
sed 's/^ *[0-9]\+.//g' tictactoeold.py >tictactoenew.py
sed -e 's/^ *[0-9]\+.//g' tictactoeold.py >tictactoenew.py
Use the -f option, and just keep the sed expressions in the file only i.e. make the file sedscript as:
s/^ *[0-9]\+.//g
and then use the sed command as:
sed -f sedscript tictactoeold.py >tictactoenew.py
-eoption is to add asedscript, not a shell script. – Byte Commander Sep 27 '16 at 11:40
