TEE(1) BSD General Commands Manual TEE(1) NAME
tee -- pipe fitting SYNOPSIS
tee [-ai] [file ...] DESCRIPTION
The tee utility copies standard input to standard output, making a copy in zero or more files. The output is unbuffered. The following options are available: -a Append the output to the files rather than overwriting them. -i Ignore the SIGINT signal. The following operands are available: file A pathname of an output file. The tee utility takes the default action for all signals, except in the event of the -i option. The tee utility exits 0 on success, and >0 if an error occurs. STANDARDS
The tee function is expected to be POSIX IEEE Std 1003.2 (``POSIX.2'') compatible. BSD

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.
