NAME

fmtmsg - display a message on stderr or system console

SYNOPSIS

fmtmsg [ -c class ] [ -u subclass ] [ -l label ] [ -s severity ] [ -t tag ] [ -a action ] text

DESCRIPTION

Based on a message's classification component, fmtmsg either writes a formatted message to stderr or writes a formatted message to the console. A formatted message consists of up to five standard com- ponents (see environment variable MSGVERB in the ENVIRONMENT section of this page.) The classification and subclass com- ponents are not displayed as part of the standard message, but rather define the source of the message and direct the display of the formatted message.

OPTIONS

The following options are supported: -c class Describes the source of the message. Valid keywords are: hard The source of the condition is hardware. soft The source of the condition is software. firm The source of the condition is firmware. -u subclass A list of keywords (separated by commas) that further defines the message and directs the display of the message. Valid keywords are: appl The condition originated in an application. This keyword should not be used in combination with either util or opsys. util The condition originated in a utility. This key- word should not be used in combination with either appl or opsys. opsys The message originated in the kernel. This key- word should not be used in combination with either appl or util. recov The application will recover from the condition. This keyword should not be used in combination SunOS 5.8 Last change: 20 Jul 1994 1 User Commands fmtmsg(1) with nrecov. nrecov The application will not recover from the condi- tion. This keyword should not be used in combi- nation with recov. print Print the message to the standard error stream stderr. console Write the message to the system console. print, console, or both may be used. -l label Identifies the source of the message. -s severity Indicates the seriousness of the error. The keywords and definitions of the standard levels of severity are: halt The application has encountered a severe fault and is halting. error The application has detected a fault. warn The application has detected a condition that is out of the ordinary and might be a problem. info The application is providing information about a condition that is not in error. -t tag The string containing an identifier for the message. -a action A text string describing the first step in the error recovery process. This string must be written so that the entire action argument is interpreted as a single argument. fmtmsg precedes each action string with the TO FIX: prefix. text A text string describing the condition. Must be writ- ten so that the entire text argument is interpreted as a single argument.

EXAMPLES

Example 1: Standard message format SunOS 5.8 Last change: 20 Jul 1994 2 User Commands fmtmsg(1) The following example of fmtmsg produces a complete message in the standard message format and displays it to the stan- dard error stream: example% fmtmsg -c soft -u recov,print,appl -l UX:cat -s error -t UX:cat:001 -a "refer to manual" "invalid syntax" produces: UX:cat: ERROR: invalid syntax TO FIX: refer to manual UX:cat:138 Example 2: Using MSGVERB When the environment variable MSGVERB is set as follows: MSGVERB=severity:text:action and Example 1 is used, fmtmsg produces: ERROR: invalid syntax TO FIX: refer to manual Example 3: Using SEV_LEVEL When the environment variable SEV_LEVEL is set as follows: SEV_LEVEL=note,5,NOTE the following fmtmsg command: example% fmtmsg -c soft -u print -l UX:cat -s note -a "refer to manual" "invalid syntax" produces: NOTE: invalid syntax TO FIX: refer to manual and displays the message on stderr.

ENVIRONMENT VARIABLES

The environment variables MSGVERB and SEV_LEVEL control the behavior of fmtmsg. MSGVERB is set by the administrator in the /etc/profile for the system. Users can override the value of MSGVERB set by the system by resetting MSGVERB in their own .profile files or by changing the value in their current shell session. SEV_LEVEL can be used in shell scripts. MSGVERB tells fmtmsg which message components to select when writing messages to stderr. The value of MSGVERB is a SunOS 5.8 Last change: 20 Jul 1994 3 User Commands fmtmsg(1) colon-separated list of optional keywords. MSGVERB can be set as follows: MSGVERB=[keyword[:keyword[:...]]] export MSGVERB Valid keywords are: label, severity, text, action, and tag. If MSGVERB contains a keyword for a component and the component's value is not the component's null value, fmtmsg includes that component in the message when writing the mes- sage to stderr. If MSGVERB does not include a keyword for a message component, that component is not included in the display of the message. The keywords may appear in any order. If MSGVERB is not defined, if its value is the null string, if its value is not of the correct format, or if it contains keywords other than the valid ones listed above, fmtmsg selects all components. MSGVERB affects only which message components are selected for display. All message components are included in console messages. SEV_LEVEL defines severity levels and associates print strings with them for use by fmtmsg. The standard severity levels shown below cannot be modified. Additional severity levels can be defined, redefined, and removed. 0 (no severity is used) 1 HALT 2 ERROR 3 WARNING 4 INFO SEV_LEVEL is set as follows: SEV_LEVEL= [description[:description[:...]]] export SEV_LEVEL description is a comma-separated list containing three fields: description=severity_keyword, level, printstring severity_keyword is a character string used as the keyword with the -s severity option to fmtmsg. SunOS 5.8 Last change: 20 Jul 1994 4 User Commands fmtmsg(1) level is a character string that evaluates to a positive integer (other than 0, 1, 2, 3, or 4, which are reserved for the standard severity levels). If the keyword severity_keyword is used, level is the severity value passed on to fmtmsg(3C). printstring is the character string used by fmtmsg in the standard message format whenever the severity value level is used. If SEV_LEVEL is not defined, or if its value is null, no severity levels other than the defaults are available. If a description in the colon separated list is not a comma separated list containing three fields, or if the second field of a comma separated list does not evaluate to a posi- tive integer, that description in the colon separated list is ignored.

EXIT STATUS

The following exit values are returned: 0 All the requested functions were executed success- fully. 1 The command contains a syntax error, an invalid option, or an invalid argument to an option. 2 The function executed with partial success, however the message was not displayed on stderr. 4 The function executed with partial success; however, the message was not displayed on the system console. 32 No requested functions were executed successfully.
