tee(1) General Commands Manual tee(1) NAME
tee - Displays the output of a program and copies it into a file SYNOPSIS
tee [-ai] file... STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: tee: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
Adds the output to the end of file instead of writing over it. Ignores the SIGINT signal. OPERANDS
Standard input is stored into, or appended to, the file specified. [Tru64 UNIX] The tee command can accept up to 20 file arguments. DESCRIPTION
The tee command reads standard input and writes to both standard output, and each specified file. The tee command is useful when you wish to view program output as it is displayed, and also want to save it in a file. The tee command does not buffer output, so you may wish to pipe the output of tee to more if more than one full screen of data is anticipated. NOTES
If a write to any file fails, the exit status of tee will be non-zero. Writes to all other specified files may be successful, and opera- tion will continue until standard input is exhausted. EXIT STATUS
The following exit values are returned: Successful completion. An error occurred. EXAMPLES
To view and save the output from a command at the same time, enter: lint program.c | tee program.lint This displays the standard output of the command lint program.c at the terminal, and at the same time saves a copy of it in the file program.lint. If program.lint already exists, it is deleted and replaced. To display and append to a file, enter: lint program.c | tee -a program.lint This displays the standard output of lint program.c at the terminal and at the same time appends a copy of it to the end of pro- gram.lint. If the file program.lint does not exist, it is created. ENVIRONMENT VARIABLES
The following environment variables affect the execution of tee: Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the corresponding value from the default locale is used. If any of the internationalization vari- ables contain an invalid setting, the utility behaves as if none of the variables had been defined. If set to a non-empty string value, overrides the values of all the other internationalization variables. Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multibyte characters in arguments). Determines the locale for the for- mat and contents of diagnostic messages written to standard error. Determines the location of message catalogues for the processing of LC_MESSAGES. SEE ALSO

tee - replicate the standard output SYNOPSIS
/usr/bin/tee /usr/bin/tee [-ai] [file]... ksh93 tee [-ail] [file]... DESCRIPTION
/usr/bin/tee /usr/bin/tee copies standard input to standard output, making a copy in zero or more files. tee does not buffer its output. The options determine if the specified files are overwritten or appended to. ksh93 The tee built-in in ksh93 is associated with the /bin and /usr/bin paths. It is invoked when tee is executed without a pathname prefix and the pathname search finds a /bin/tee or /usr/bin/tee executable. tee copies standard input to standard output and to zero or more files. The options determine whether the specified files are overwritten or appended to. The tee utility does not buffer output. If a write to a file fails, tee continues to write to other files although it exits with a non-zero exit status. The number of file operands that can be specified is limited by the underlying operating system. OPTIONS
/usr/bin/tee The following options are supported by /usr/bin/tee: -a Appends the output to the files rather than overwriting them. -i Ignores interrupts. ksh93 The following options are supported by the tee built-in command in ksh93: -a Appends the output to the files rather than overwriting them. --append -i Ignores SIGINT signal. --ignore-interrupts -l Sets the standard output to be line buffered. --line-buffer OPERANDS
The following operands are supported: file A path name of an output file. Processing of at least 13 file operands are supported. USAGE
See largefile(5) for the description of the behavior of tee when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of tee: LANG, LC_ALL, LC_CTYPE, LC_MES- SAGES, and NLSPATH. EXIT STATUS
/usr/bin/tee The following exit values are returned by /usr/bin/tee: 0 The standard input was successfully copied to all output files. >0 The number of files that could not be opened or whose status could not be obtained. ksh93 The following exit values are returned by tee in ksh93: 0 Successful completion. >0 An error occurred.
