1 Answer

You can use

perl -pne '$_=~s/\n//g; $_=~s/\+//g; END{print "\n";}' filename.txt

Explanation:

• perl -pne reads the file line-wise, performs the commands given and outputs the content of $_
• comp; removes the newline character at the end of the line
• $_=~s/\+//g; removes the + sign from the line
• END{print "\n";} adds a newline at the end of the file
