subtitle...fun with sed
I have a list of changes to make to a file...
dc rc
------------- -------
15T6145V DELETED
NATL19502 DELETED
Q10MR11/FL12V DELETED
Q1500T3/CL120 DELETED
and things work until I get to the 3rd item which has a forward
slash and it fails to substitute with commands like below...
sed -i "s%${dc}%${rc}%g" ARsalesorderdetails.csv
and
sed -i "s/${dc}/${rc}/g" ARsalesorderdetails.csv
The latter producing error on screen...
sed: -e expression #1, char 17: unknown option to `s'
While the former simply doesn't complain but doesn't make the change
either.
Hmm, it should work using a delimeter other than '/' or escaping the
'/'. Escaping the '/' is a bit more of a pain than just changing
delimeters, as long as you know that whatever delimeter you pick won't
be in the strings you are substituting.
It seems to work for me:
$ dc="Q10MR11/FL12V"; rc=DELETED; echo "dc=${dc}"; echo
"rc=${rc}"; \
echo "This is some Q10MR11/FL12V text." | sed "s%${dc}%${rc}%g"
dc=Q10MR11/FL12V
rc=DELETED
This is some DELETED text.
