Hi, all,

I wonder if I can use sed to insert a string which has a colon.

I have a txt file a.txt like the following

TRAIN/DR1/FCJF0/SI1027.MFC
TRAIN/DR1/FCJF0/SI1657.MFC

I want to insert a string C:/TIMIT/TIMIT at the begining of each line.

I use the commond:
TIM=C\:/TIMIT/TIMIT
sed "s:^:$TIM/:" < a.txt > b.convert

and I got the error "sed -e expression #1, char 7: unknow option to 's'".
it seems because there is a colon in $TIM,
if I use C\:/TIMIT/TIMIT instead of variable $TIM, in command
sed "s:^:$TIM/:" < a.txt > b.convert
it works.

and I also tried
sed "s:^:$*****}/:" < a.txt > b.convert
still got the same problem.

so I wonder how I can insert a string which has a colon in a txt file.

Thanks,
Jenny

Use a different separator.

sed "s|^|$*****}/|" < a.txt > b.convert

Yeah, it works, thanks.
