# The sed expression is intended to replace this: | |
# %CPU %MEM COMMAND | |
# 0.0 0.1 some really really really long process args | |
# with this: | |
# %CPU %MEM COMMAND | |
# 0.0 0.1 some reall...ocess args | |
# In the sed regex: | |
# [^[:space:]]* means "a sequence non-whitespace characters" | |
# \s* means "a sequence of whitespace characters" | |
# The sed regex matches the first and last 10 characters of the process args, | |
# and concatenates them with an ellipsis ... for easier viewing. | |
