Using sed I need to replace variables in an HTML document.

The following is what i am using:

cat $email_temp\
 | sed 's/\$message_entry/Flex File Export completed successfully for'"$run_date"'./g'\
 | sed 's/\$run_date/'"$run_date"'/g'\
 | sed 's/\$flex_file_new_count/\'"$flex_file_new_count"'/g'\
 | sed 's/\$exported_file_count/'"$exported_file_count"'/g'\
 | sed 's/\$date_data/\'"$date_data"'/g'\
 | sed 's/\$flex_file_old_count_data/\'"$flex_file_old_count_data"'/g' > $email_body

    It's hard to say what you're doing wrong when we don't know what you're trying to do. Please edit your question and describe what you're trying to do, and how what you've tried behaved differently than what you want. Nov 4, 2019 at 1:03

    You have mismatch because of ' character.

  • Does run date include any slashes?

    Whenever you inject stuff externally u need to vet them carefully. Check if your variable is having newlines. Especially $flex_file_new_count. Nov 4, 2019 at 14:58

As pointed out in the comments by @unxnut, there are three escaped single quotes \' in your command which should not be escaped. Thus sed cannot find the matching closing single quote and fails.

Try this (with quoted variables $email_temp, $email_body and one sed call):

sed -e 's/\$message_entry/Flex File Export completed successfully for'"$run_date"'./g'\
 -e 's/\$run_date/'"$run_date"'/g'\
 -e 's/\$flex_file_new_count/'"$flex_file_new_count"'/g'\
 -e 's/\$exported_file_count/'"$exported_file_count"'/g'\
 -e 's/\$date_data/'"$date_data"'/g'\
 -e 's/\$flex_file_old_count_data/'"$flex_file_old_count_data"'/g' "$email_temp" > "$email_body"
