In order to parse certain log file and make a plot of sequential numbers, I need to filter out the lines with numbers which appearing lower than in the previous lines.
For example, given the list of lines with integers:
62 116 33 20 61 67 89 82 15 109 73 101 115 120 41 103 94 122
Note: File can be generated by
hexdump -n100 -e '1/1 "%d" "\n"' /dev/urandom | grep -v ^-.
I'd like to filter out (remove) the numbers that way, so all of them are sequential (so they look kind of sorted).
Ideally if the command will take into the account all the previous lines.
Here is my expected results:
62 116 120 122
If the command won't filter correctly after first time, I can always re-run it couple of times.
Here is my attempt based on this post:
:g/^/ if getline(line('.')-1) < getline('.') | delete | endif
but it removes all the lines instead.
How I should correct my command? Or what other approach I could use?
