grep

It filters out output

# -C return 5 lines up and 5 lines down the line where the criteria is matched
cat text.txt  | grep -C 5 "password"`

TRouble shootung:

file upgrader_default.log  
xxd -l 64 upgrader_default.log

If it says something like Little-endian UTF-16 Unicode text, use one of these:

grep -a "Exiting" upgrader_default.log

or better:

iconv -f UTF-16LE -t UTF-8 upgrader_default.log | grep "Exiting"

with context:

iconv -f UTF-16LE -t UTF-8 upgrader_default.log | grep -C 2 "Exiting"
