Arcgsh workd together with the compress 4.3 port by Dale Schumacher (dal@syntel.uucp).
Compress serves to compress or decompress single files. It does not pack several files into an archive, but converts a single file into a compressed representation and vice versa.
When compressing a file compress appends the original file name with the letter .Z, if possible as an extension. Upon decompression the Z will be removed. The following examples may illustrate this;
Originaldatei $&rarr#longrightarrow;$ komprimiert $&rarr#longrightarrow;$ dekomprimiert FOO $&rarr#longrightarrow;$ FOO.Z $&rarr#longrightarrow;$ FOO FOO.C $&rarr#longrightarrow;$ FOO.CZ $&rarr#longrightarrow;$ FOO.C FOO.CC $&rarr#longrightarrow;$ FOO.CCZ $&rarr#longrightarrow;$ FOO.CC FOO.CCC $&rarr#longrightarrow;$ FOO.CCZ $&rarr#longrightarrow;$ FOO.CC Attention!
Please note that upon compression of a file with an extension of three characters the last character will be lost!
If compress cannot compress a file the file itself — and its name, too — will stay unchanged. Examples for files that cannot be compressed are already compressed files or very small ones.
