Keep a count of bytes read rather than comparing pointers since the variable_buffer might get reallocated. Bug and patch by Ken Tossell <ken@tossell.net> Regression tests by Dmitry Goncharov <dgoncharov@users.sf.net> Tweaked by Paul Smith <psmith@gnu.org> * src/function.c (func_file): Use bytes read rather than a pointer. * tests/scripts/functions/file: Provide various tests for reading empty files, files with/without newlines, and large files.

# of shell features. Since we already have Perl to run the tests, use that.

# The arguments represent a set of steps that will be run one at a time.
|
|
# Each step consists of an operator and argument.
|
|
#
|
|
# It supports the following operators:
|
|
# out <word> : echo <word> to stdout with a newline
|
|
# raw <word> : echo <word> to stdout without adding anything
|
|
# file <word> : echo <word> to stdout AND create the file <word>
|
|
# dir <word> : echo <word> to stdout AND create the directory <word>
|
|
# rm <word> : echo <word> to stdout AND delete the file/directory <word>
|
|
# wait <word> : wait for a file named <word> to exist
|
|
# tmout <secs> : Change the timeout for waiting. Default is 4 seconds.
|
|
# sleep <secs> : Sleep for <secs> seconds then echo <secs>
|
|
# fail <err> : echo <err> to stdout then exit with error code err
|
|
#
|
|
# If given -q only the "out" command generates output.
|
|
|
|
# Force flush
