Question

I am having a little problem with putting a regex inside a sed command, this is my code:

RAW_LIST_B=`echo $RAW_LIST_A | sed s/[0-9a-f]{8} / /g`

And i get this error :

sed: -e expression #1, char 13: unterminated `s' command

I am not sure how to quote the [0-9a-f]{8} so that it removes all 8 digit hex numbers and trailing space from RAW_LIST_A

Thanks,

Answer 1

You should enclose sed experssion into a quotes so it will be one string parameter passed to sed by shell

RAW_LIST_B=`echo $RAW_LIST_A | sed "s/[0-9a-f]\{8\} //g"`

Sample output:

$ echo "hello a5a5a5a6 world" | sed "s/[0-9a-f]\{8\} //g"
hello world
