Full Discussion: What type of error is this?
Operating Systems Linux Red Hat What type of error is this? Post 302541790 by botao on Monday 25th of July 2011 06:26:17 PM

Lightbulb a read system call returned -1

- this error means that a read() system call returned -1 ;

- when the read() system call encounters an error condition, it returns -1 ;

- the external variable 'errno' holds a code that helps explain the reason why read() failed ;

- in you case , the code is 104 ;

- do a
Code:
grep 104 /usr/include/errno.h

to see what it means ;

good luck, and success !

NAME
zgrep - search possibly compressed files for a regular expression SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename... DESCRIPTION
Zgrep invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code: (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other 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 the GREP environment variable is set, zgrep uses it as the grep program to be invoked. EXIT CODE
2 - An option that is not supported was specified. AUTHOR
