    NAME

    
    
    zcmp
    
     
    zdiff
    
     - compare compressed files
    
     
    

    SYNOPSIS

    zcmp [options ] file [file2 ]
    zdiff [options ] file [file2 ]  

    DESCRIPTION

    zcmp and zdiff are filters that invoke cmp(1) or diff(1) respectively to compare compressed files. Such files generally have a ``Z'' or ``gz'' extension (both the compress(1) and gzip(1) formats are supported). Any options that are specified are passed to cmp(1) or diff(1).

    If only file1 is specified, it is compared against a file with the same name, but with the extension removed. When both file1 or file2 are specified, either file may be compressed.  

    ENVIRONMENT

    TMPDIR
    Directory in which to place temporary files. If unset, /tmp is used.

     

    FILES

    /tmp/zcmp.XXXXXXXXXX
    Temporary file for zcmp
    /tmp/zdiff.XXXXXXXXXX
    Temporary file for zdiff

     

    SEE ALSO

    cmp(1), compress(1), diff(1)  

    CAVEATS

    zcmp and zdiff rely solely on the file extension to determine what is, or is not, a compressed file. Consequently, the following are not supported as arguments:

    directories
    device special files
    filenames indicating the standard input
    (``-'' )
