|Linux / Unix Command: zgrep|
NAMEzgrep - search possibly compressed files for a regular expression
SYNOPSISzgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTIONZgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is specified, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and fed to grep.
If zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses it as the grep program to be invoked. For example:
SEE ALSOgrep(1), egrep(1), fgrep(1), zdiff(1), zmore(1), znew(1), zforce(1), gzip(1), gzexe(1)
Important: Use the man command (% man) to see how a command is used on your particular computer.
