<para>The <EnVar>CYGWIN</EnVar> environment variable is used to configure
|
|
many global settings for the Cygwin runtime system. It contains the options
|
|
listed below, separated by blank characters. Many options can be turned off
|
|
by prefixing with <literal>no </literal>.</para>

<para><FirstTerm>(no)binmode</FirstTerm> - if set, non-disk

(e.g. pipe and COM ports) file opens default to binary mode
|
|
(no CR/LF/Ctrl-Z translations) instead of text mode.
|
|
Defaults to set (binary mode). This option must be set
|
|
before starting a Cygwin shell to have an effect on redirection.

<para><FirstTerm>(no)envcache</FirstTerm> - If set, environment variable
|
|
conversions (between Win32 and POSIX) are cached. Note that this is may
|
|
cause problems if the mount table changes, as the cache is not invalidated
|
|
and may contain values that depend on the previous mount table
|
|
contents. Defaults to set.</para>

<para><FirstTerm>(no)export</FirstTerm> - if set, the final values of these

<para><FirstTerm>error_start:filepath</FirstTerm> - if set, runs <filename>filepath</filename>
|
|
when cygwin encounters a fatal error. This is useful for debugging.
|
|
<filename>filepath</filename> is usually set to the path to the <filename>gdb</filename>
|
|
program.</para>
|
|
<para><FirstTerm>(no)glob[:ignorecase]</FirstTerm> - if set, command line arguments
|
|
containing UNIX-style file wildcard characters (brackets, question mark,
|
|
asterisk, escaped with \) are expanded into lists of files that match
|
|
those wildcards.
|
|
This is applicable only to programs running from a DOS command line prompt.
|
|
Default is set.</para>
|
|
<para>This option also accepts an optional <literal>[no]ignorecase</literal> modifer.
|

If supplied, wildcard matching is case insensitive. The default is <literal>noignorecase</literal></para>

<para><FirstTerm>(no)ntea</FirstTerm> - if set, use the full NT Extended
|
|
Attributes to store UNIX-like inode information.
|
|
This option only operates under Windows NT. Defaults to not set. </para>

<listitem>
|
|
<para><FirstTerm>(no)ntsec</FirstTerm> - if set, use the NT security
|
|
model to set UNIX-like permissions on files and processes. The
|
|
file permissions can only be set on NTFS partitions. FAT doesn't
|
|
support the NT file security. For more information, read the documentation
|
|
in <citation>ntsec.sgml</citation>.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para><FirstTerm>(no)smbntsec</FirstTerm> - if set, use `ntsec' on remote
|
|
drives as well (this is the default). If you encounter problems with NT shares
|
|
or Samba drives, setting this to `nosmbntsec' could help. In that case the
|
|
permission and owner/group information is faked as on FAT partitions.
|
|
A reason for a non working ntsec on remote drives could be insufficient
|
|
permissions of the users. Since the needed user rights are somewhat dangerous
|
|
(SeRestorePrivilege) it's not always an option to grant that rights to users.
|
|
However, this shouldn't be a problem in NT domain environments.</para>

<listitem>
|
|
<para><FirstTerm>(no)reset_com</FirstTerm> - if set, serial ports are reset
|
|
to 9600-8-N-1 with no flow control when used. This is done at open
|
|
time and when handles are inherited. Defaults to set.</para>
|

</listitem>

<listitem>

<para><FirstTerm>(no)strip_title</FirstTerm> - if set, strips the directory

part off the window title, if any. Default is not set.</para>

</listitem>
|
|
<listitem>
|
|
<para><FirstTerm>(no)title</FirstTerm> - if set, the title bar
|
|
reflects the name of the program currently running. Default is not
|
|
set. Note that under Win9x the title bar is always enabled and it is
|
|
stripped by default, but this is because of the way Win9x works. In
|
|
order not to strip, specify <literal>title</literal> or <literal>title
|
|
nostrip_title</literal>.</para>

</listitem>

<listitem>
|
|
<para><FirstTerm>(no)tty</FirstTerm> - if set, Cygwin enables extra support
|
|
(i.e., termios) for UNIX-like ttys.
|
|
It is not compatible with some Windows programs.
|
|
Defaults to not set, in which case the tty is opened in text mode
|
|
with ^Z as EOF. Note that this has been changed such that ^D works as
|
|
expected instead of ^Z, and is settable via stty.
|
|
This option must be specified before starting a Cygwin shell
|
|
and it cannot be changed in the shell.</para>

<para><FirstTerm>(no)winsymlinks</FirstTerm> - if set, Cygwin creates
|
|
symlinks as Windows shortcuts with a special header and the R/O attribute
|
|
set. If not set, Cygwin creates symlinks as plain files with a magic number,
|
|
a path and the system attribute set. Defaults to set.</para>
