[SOLVED] Unix command to prepend text to a file

Issue

Is there a Unix command to prepend some string data to a text file?

Something like:

prepend "to be prepended" text.txt

id='dv3'>

Solution

sed -i.old '1s;^;to be prepended;' inFile

• -i writes the change in place and take a backup if any extension is given. (In this case, .old)
• 1s;^;to be prepended; substitutes the beginning of the first line by the given replacement string, using ; as a command delimiter.
