# 'cat' with ASCII progress bar

# (c) Henrik Theiling

BAR_VERSION=1.4
|
|
||||||
|
|
||||||
# Synopsis:
|
|
||||||
# 'bar' works just like 'cat', but shows a progress bar in ASCII art on stderr.
|
|
||||||
# The script's main function is meant to be usable in any Bourne shell to be
|
|
||||||
# suitable for install scripts without the need for any additional tool.
|
|
||||||
#
|
|
||||||
# Shell Script Usage: bar [options] [files]
|
|
||||||
# Options:
|
|
||||||
# -h displays help
|
|
||||||
# ...
|
|
||||||
#
|
|
||||||
# Examples:
|
|
||||||
# Normal pipe:
|
|
||||||
#
|
|
||||||
# : bar mypack.tar.bz2 | tar xjpf -
|
|
||||||
#
|
|
||||||
# Individual pipe for each file:
|
|
||||||
#
|
|
||||||
# : bar -c 'tar xjpf -' mypack1.tar.bz2 mypack2.tar.bz2
|
|
||||||
#
|
|
||||||
# Individual pipe, using ${bar_file} variable:
|
|
||||||
#
|
|
||||||
# : bar -c 'echo ${bar_file}: ; gzip -dc | tar tvf -' \
|
|
||||||
# : -e .tar.gz \
|
|
||||||
# : file1 file2 file3 file4 file5 \
