I use the following sed command to remove the line number string from file
sed -i s'/line number//g' file but what I need to change in sed syntax in order to remove the line number only if it exist in the last line of the file?

Deleting line using sed To delete a line, we'll use the sed “d” command. Note that you have to declare which line to delete. Otherwise, sed will delete all the lines.
txt (if it ends with EOF , or \n and then EOF ), the number of lines in new_file. txt may be the same (as file. txt ) after this command (this happens when there is no \n ) - in any case, the contents of the last line is deleted.
sed -e :a -e '/^\n*$/{$d;N;ba' -e '}' : this will remove all the blank lines from end of the file. sed '$d' : this will remove the last line.
I'm not sure I fully understand your question, however this can help you :
sed -i '$ s/line number//g' file This will perform substitution only on last line (because of $), replacing line number by nothing.
man sed, section Addresses can help you understand how to apply sed commands on part of the text.
