strip is ashell command for removing information frombinary executable programs andobject files that is not required forexecution – typically includingdebugging data,symbol tables,relocation information, and othermetadata. The resulting file will have a smallersize, this is also known as astripped binary.^[1]

Usingstrip can enhance the security of an executable by making it more difficult toreverse-engineer. The absence of symbol and debugging information complicates theprogram analysis of the binary.

The effect ofstrip can also be achieved via acompiler orlinker to perform the same process.^[2] For example, in theGNU C compiler (gcc), this is done via the-s option.^[2]

The command is available inUnix,Plan 9, andUnix-like systems. TheGNU Project includes an implementation in theGNU Binutils package. The command has been implemented in to other operating systems includingWindows.
