Top Forums UNIX for Dummies Questions & Answers Matching exact string with blank space using grep Post 302465697 by Scrutinizer on Saturday 23rd of October 2010 12:30:23 PM

See man grep on Solaris. The xpg4 version has a -q option.

What do you mean map? This puts it in the variable $grep
You could do this:
Code:
#!/bin/sh
export PATH="/usr/xpg4/bin:$PATH"

Actually, I reckon this would be a good way to start a script on Solaris:
Code:
#!/usr/xpg4/bin/sh
export PATH="/usr/xpg4/bin:$PATH"

Using XPG4 is the closest you can come to Posix compliance and should give you good portability. You would likely only need to change the shebang (#!) on the first line if you want to run it on another platform.

NAME
sh - Shell, the standard command language interpreter DESCRIPTION
[Tru64 UNIX] Tru64 UNIX provides two command interpreters with the name sh. The XCU5.0 and POSIX.2 compliant command interpreter sh is available in the file /usr/bin/posix/sh and is described in the sh(1p) reference page. The Bourne shell, historically known as sh, is available in the file /usr/bin/sh and is described in the sh(1b) reference page. [Tru64 UNIX] Your initial, or login, shell is determined by your entry in the file /etc/passwd. This file can be changed only by your sys- tem administrator. You must use whatever procedures are in place at your location to have this entry changed. [Tru64 UNIX] If available on your system, you may use the passwd -s or the chsh commands to change your login shell. Note This option is not available if your site manages passwords through the Network Information Service (NIS) facility. Check with your system administrator. [Tru64 UNIX] Subsequent shells spawned from the initial shell depend on the value in the environment variable BIN_SH. If this variable is set to xpg4, the POSIX shell is started. If this variable is set to svr4, an SVR4 compliant version of the shell is started. If this vari- able is unset, the Bourne shell is started. If this variable is set to any other value, an error is reported and the results are unpre- dictable. See the EXAMPLES section for information on setting this variable. NOTES
[Tru64 UNIX] With Tru64 UNIX Version 4.0 the Korn shell, /usr/bin/ksh is the same as the POSIX shell /usr/bin/posix/sh. RESTRICTIONS
[Tru64 UNIX] The file /etc/shells must include entries for both the POSIX shell /usr/bin/posix/sh and the Bourne shell, /usr/bin/sh. If this file is incorrect, see your system administrator. EXAMPLES
Using the Bourne, Korn, or POSIX shell, to set the variable BIN_SH to use the POSIX/ XCU5.0compliant shell, enter: BIN_SH=xpg4 export BIN_SH Using the Bourne, Korn, or POSIX shell, to set the variable BIN_SH to use the SVR4 compliant shell, enter: BIN_SH=svr4 export BIN_SH Using the Bourne, Korn, or POSIX shell, to unset the variable BIN_SH, enter: unset BIN_SH Using the C/ shell, to set the variable BIN_SH to use the POSIX/XCU5.0 compliant shell, enter: setenv BIN_SH xpg4 Using the C/ shell, to set the variable BIN_SH to use the SVR4 compliant shell, enter: setenv BIN_SH svr4 Using the C/ shell, to unset the variable BIN_SH, enter: unsetenv BIN_SH FILES
