annotate src/bzip2-1.0.6/bzgrep.1 @ 83:ae30d91d2ffe
Replace these with versions built using an older toolset (so as to avoid ABI compatibilities when linking on Ubuntu 14.04 for packaging purposes)

|
|
Chris@4
|
22 .IR Bzgrep
|
|
Chris@4
|
23 is used to invoke the
|
|
Chris@4
|
24 .I grep
|
|
Chris@4
|
25 on bzip2-compressed files. All options specified are passed directly to
|
|
Chris@4
|
26 .I grep.
|
|
Chris@4
|
27 If no file is specified, then the standard input is decompressed
|
|
Chris@4
|
28 if necessary and fed to grep.
|
|
Chris@4
|
29 Otherwise the given files are uncompressed if necessary and fed to
|
|
Chris@4
|
30 .I grep.

|
Chris@4
|
48 program to be invoked. For example:
|
|
Chris@4
