Unable to copy a file with '$' in name in Linux

Question

Inside of my Linux directory, I have a file named TopSample$Config.class. Whenever I try to copy this file to another location/directory, it is not allowing m

Answer 1

Or replace the offending character with the filename metacharacter of '?', meaning "any one character". Note that while this might be more convenient and requires the fewest keystrokes, be aware that a filename of TopSample?Config.class will also match TopSampleaConfig.class, TopSamplebConfig.class, TopSamplecConfig.class, etc.

Answer 2

The shell will interpret $Config as a variable. And it will expand to empty string.
You can put single quotes around to keep the literal value:

cp 'TopSample$Config.class' /home/praveen/com/config/

Another way is to escape the $(dollar sign) by using \(backslash)

cp TopSample\$Config.class /home/praveen/com/config/

Answer 3

Put single quotes around the filename.

cp 'TopSample$Config.class' /home/praveen/com/config
