Top Forums Shell Programming and Scripting Trouble with tee command to capture script outputs Post 302288220 by muthubharadwaj on Monday 16th of February 2009 06:09:00 PM

Your comment "all commands except the last are executed in a sub-shell" explains the behavior, which is what I though though was not sure. What exactly is the "last one", the tee command itself, the rightmost one I guess? In my context, the command which I run and pipe the output to using tee is a "shell function" defined within the script - not a script different from the one that calls it. Usually functions run in the same shell as the one in which the script calling them runs. Including pipe seems to make a difference ot the bahavior. Thanks anyway for your time and effort in responding.

split [OPTION]... [INPUT [PREFIX]] DESCRIPTION
Output fixed-size pieces of INPUT to PREFIXaa, PREFIXab, ...; default size is 1000 lines, and default PREFIX is 'x'. With no INPUT, or when INPUT is -, read standard input. Mandatory arguments to long options are mandatory for short options too. -a, --suffix-length=N generate suffixes of length N (default 2) --additional-suffix=SUFFIX append an additional SUFFIX to file names -b, --bytes=SIZE put SIZE bytes per output file -C, --line-bytes=SIZE put at most SIZE bytes of lines per output file -d, --numeric-suffixes[=FROM] use numeric suffixes instead of alphabetic; FROM changes the start value (default 0) -e, --elide-empty-files do not generate empty output files with '-n' --filter=COMMAND write to shell COMMAND; file name is $FILE -l, --lines=NUMBER put NUMBER lines per output file -n, --number=CHUNKS generate CHUNKS output files; see explanation below -u, --unbuffered immediately copy input to output with '-n r/...' --verbose print a diagnostic just before each output file is opened --help display this help and exit --version output version information and exit SIZE is an integer and optional unit (example: 10M is 10*1024*1024).
