htop output to human readable file

问题:

I've tried piping htop to a text file (e.g. htop > text.txt) but it gives me text garbled by formatting strings (see below). Is there a way to get nicer, human readable output?

回答1:

htop author here.

No, there's no "nice" way to get the output of htop piped into a file. It is an interactive application and uses terminal redraw routines to produce its interface (therefore, piping it makes as much sense as, for example, piping vim into a text file -- you'll get similar results).

To get the information about your processes in a text format, use "ps". For example, ps auxf > file.txt gives you lots of easy to parse information (or ps aux if you do not wish tree-formatting -- see man ps for more options).

回答2:

htop outputs ANSI escape code to use colors and move the cursor around the terminal. There is a great command line program aha that can be used to convert ANSI into HTML.

Ubuntu/Debian installation

apt-get install aha

Save htop output as HTML file

echo q | htop | aha --black --line-fix > htop.html

回答3:

I have had the same need, and ended up using top instead of htop a is provides a batch mode via the -b flag.

-b : Batch mode operation Starts top in 'Batch mode', which could be useful for sending output from top to other programs or to a file. In this mode, top will not accept input and runs until the iterations limit you've set with the '-n' command-line option or until killed.

So for example:

top -b -n 1

Hope this helps even if this is not using htop.

回答4:

This command outputs plain text. (It requires installing aha and html2text.)

echo q | htop -C | aha --line-fix | html2text -width 999 | 
grep -v "F1Help\|xml version=" > file.txt

回答5:

You can also use script prior to running htop in a mode that will redirect timings to a file for later playback. In the realm of 'yet another work around' and 'good for show and tell'.

script -t -a /var/tmp/script.htop.out 2> /var/tmp/script.htop.out.timings
htop 

Then to playback

scriptreplay /var/tmp/script.htop.out.timings /var/tmp/script.htop.out

回答6:

Install recode first, then encode it to utf-8:

$htop | recode utf-8 > test.txt

Then cat the file and you should be good.

回答7:

This may sound really noobish, however, if you have multiple monitors you could have htop running while "record my desktop" is capturing that area. Its more of a video and may not help with searching and sorting but it would look nice and pretty.
