NAME
zcat — expand and
concatenate data
SYNOPSIS
zcat |
[file ...] |
DESCRIPTION
The zcat utility will write to standard
output the uncompressed form of files that have been compressed using the
compress(1) utility. It is the equivalent of
uncompress(1) -c . Input files are
not affected.
OPTIONS
None.
OPERANDS
The following operand is supported:
- file
- The pathname of a file previously processed by the compress(1) utility. If file already has the .Z suffix specified, it is used as submitted. Otherwise, the
STDIN
The standard input will be used only if no file operands are specified, or if a file operand is "-".
INPUT FILES
Input files must be compressed files that are in the format produced by the compress(1) utility.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of
zcat :
LANG- Provide a default value for the internationalisation variables that are
unset or null. If
LANGis unset or null, the corresponding value from the implementation-dependent default locale will be used. If any of the internationalisation variables contains an invalid setting, the utility will behave as if none of the variables had been defined. LC_ALL- If set to a non-empty string value, override the values of all the other internationalisation variables.
LC_CTYPE- Determine the locale for the interpretation of sequences of bytes of text data as characters (for example, single- as opposed to multi-byte characters in arguments).
LC_MESSAGES- Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error.
NLSPATH- Determine the location of message catalogues for the processing of LC_MESSAGES .
ASYNCHRONOUS EVENTS
