Re: Searching the last 5 field of each line in a csv, a puzzling output.
csvcut https://github.com/zigazou/csvcut may be useful. It's like the "cut" command for csv input. Some other tools that may be of interest, possibly installable by apt / synaptic: csvkit and csvtool Note, I've not used any of these, and am not vouching for them, but it seems like they co...

Re: Wordle Solver
Not a "solver" but (a variation on) the game itself, to be run in terminal window. It's not perfect but I've stopped working on it, it's good enough for me to play on my own system occasionally :-) #!/bin/bash if [ ! -z "$1" ]; then # make sure $1 is an integer ... ntest=$(expr $...

Re: need batch command mp4 to mp3 (remove video)
ffmpeg -i video.mp4 -vn -acodec libmp3lame -ac 2 -ab 160k -ar 48000 audio.mp3 it works great, but only processes one file at a time. I would like a command, file, or script that is capable of removing the video on all .mp4 files in a directory and leaving only .mp3 files. can this command be used f...

Re: bash script that randomly prints numbers between 1 and 10 without repetition
This entire exercise is much simpler if you pre-randomize the results:
Code: Select all
#!/bin/bash
echo "3 5 2 1 4 8 9 7 6 10"

Re: wget with recursive, overwrite & erobots off
The "problem" is that -O is not overwrite. It specifies the output file name.
Since your source is apparently a directory, try putting a / at the end of it. Then -r seems to not complain about it being a directory. In your particular case:

Sorry if this is a redundent question. I've googled many phrases trying to find out how to do the following: use wget to download a series of pages off my local server.

Re: Bash script to advise when Internet restored
If you suspect line-ending problems, check your file size. I copied your code at the end and have a 1023-byte file, which does execute correctly (other than paplay which I do not have).Busker wrote: ⤴Fri Dec 04, 2020 7:33 pmCode: Select all

Re: Need help to create login script to modify /etc/hosts
I know I'm a little late to reply. If you've not already found a solution, here's another suggestion which may or may not help your particular case. You could put a few entries in /etc/crontab to run, say, (a) M-F at 8am (or whenever) to copy your restricted hosts file, then (b) at 4pm to copy your ...

Re: cannot cp file to directory with spaces in name
I know it's already been asked and answered. The two problems were: 1) You were escaping the quotation marks. "/home/bobi/tmp/\"dir with spaces\"" is not the same as /home/bobi/tmp/"dir with spaces" The first has the quotation marks in the directory name, which is not w...

NOTE I'm not running Mint 19.1 Cinnamon. I do use a dual-monitor setup. My desktop is XFCE. I have noticed that the behavior seems largely program-dependent. In general, most programs seem to open their window on whatever monitor the mouse is currently positioned. So I usually position the mouse to ...

Re: Do I really need to encrypt home if I have full disk encryption?
2) Are there any benefits to having the `home` encrypted with encfs if full-disk LUKS encryption is also enabled? Not in a single user scenario. In a multi-user scenario it gives protection from other users (including administrators) accessing your files. Ideally, yes. However in testing (on LM18) ...

Re: New to automation/scripting, Switch to python?
Just a suggestion to make it a little more readable, I prefer using echo -e "blahblah\n\n" -- the \n will insert a newline for you. In fact you could even combine the command you're running along with the echo command. Such as: echo -e "Sockets:\n\n\n$(sudo systemctl -l|grep .socket)\...
