Je fais peindre mon mur en ce moment. Voilà où ça en est ! Je suis plutôt content-e ! Hâte de le voir fini !

- Supervise command (run every 2s)
watch "ls -larth"
- Kill program using one port
sudo fuser -k 8000/tcp
- Limit memory usage for following commands
ulimit -Sv 1000 # 1000 KBs = 1 MB
ulimit -Sv unlimited # Remove limit
- Rename selected files using a regular expression
rename 's/\.bak$/.txt/' *.bak
- Get full path of file
readlink -f file.txt
- List contents of tar.gz and extract only one file
tar tf file.tgz
tar xf file.tgz static
- List files by size
ls -lS
- Nice trace route
mtr google.com
- Find files tips
find . -size 20c # By file size (20 bytes)
find . -name "*.gz" -delete # Delete files
find . -exec echo {} \; # One file by line
./file1
./file2
./file3
find . -exec echo {} \+ # All in the same line
./file1 ./file2 ./file3
- Print text ad infinitum
yes
yes hello
- Who is logged in?
w
- Prepend line number
ls | nl
- Grep with Perl like syntax (allows chars like \t)
grep -P "\t"
- Cat backwards (starting from the end)
tac file
- Check permissions of each directory to a file
It is useful to detect permissions errors, for example when configuring a web server.
namei -l /path/to/file.txt
- Run command every time a file is modified
while inotifywait -e close_write document.tex
do
make
done
- Copy to clipboard
cat file.txt | xclip -selection clipboard
- Spell and grammar check in Latex
detex file.tex | diction -bs
You may need to install the following: sudo apt-get install diction texlive-extra-utils.
- Check resources' usage of command
/usr/bin/time -v ls
- Randomize lines in file
cat file.txt | sort -R
cat file.txt | sort -R | head # Pick a random sambple
# Even better (suggested by xearl in Hacker news):
shuf file.txt
- Keep program running after leaving SSH session
If the program doesn't need any interaction:
nohup ./script.sh &
If you need to enter some input manually and then want to leave:
./script.sh
<Type any input you want>
<Ctrl-Z> # send process to sleep
jobs -l # find out the job id
disown -h jobid # disown job
bg # continue running in the background
Of course, you can also use screen or tmux for this purpose.
- Run a command for a limited time
timeout 10s ./script.sh
# Restart every 30 minutes
while true; do timeout 30m ./script.sh; done
- Combine lines from two sorted files
comm file1 file2
Prints these three columns:
Lines unique to file1.
Lines unique to file2.
Lines both in file1 and file2.
With options -1, -2, -3, you can remove each of these columns.
- Split long file in files with same number of lines
split -l LINES -d file.txt output_prefix
- Flush swap partition
If a program eats too much memory, the swap can get filled with the rest of the memory and when you go back to normal, everything is slow. Just restart the swap partition to fix it:
sudo swapoff -a
sudo swapon -a
- Fix ext4 file system with problems with its superblock
sudo fsck.ext4 -f -y /dev/sda1
sudo fsck.ext4 -v /dev/sda1
sudo mke2fs -n /dev/sda1
sudo e2fsck -n <first block number of previous list> /dev/sda1
- Create empty file of given size
fallocate -l 1G test.img
- Manipulate PDFs from the command line
To join, shuffle, select, etc. pdftk is a great tool:
pdftk *.pdf cat output all.pdf # Join PDFs together
pdftk A=in.pdf cat A5 output out.pdf # Extract page from PDF
You can also manipulate the content with cpdf:
cpdf -draft in.pdf -o out.pdf # Remove images
cpdf -blacktext in.pdf -o out.pdf # Convert all text to black color
- Monitor the progress in terms of generated output
# Write random data, encode it in base64 and monitor how fast it is being sent to /dev/null
cat /dev/urandom | base64 | pv -lbri2 > /dev/null
# pv options:
# -l, lines
# -b, total counter
# -r, show rate
# -i2, refresh every 2 seconds
- Find packages that have a given file in Ubuntu
apt-file update
apt-file search dir/file.h
Je n'achète que du SOL car je considère que je veux investir sur un truc avec une volatilité assez élevée (+ élevée que BTC ou ETH).
Et je pense que Solana est un Ethereum killer. Mon average cost c'est 121€, aujourd'hui on est à 158€ quand j'écris. Pas super rentable mais bon je garde espoir !
Edit: et je crois pas que Bitcoin dominera toute la vie. Ça finira par tomber. Il suffit de quelques baleines qui bougent et c'est terminé. Ethereum et Solana ont l'air d'être des techno plus intéressantes. Mais c'est mon avis de pas expert-e du sujet.
Je pense que les affiches ne sont pas concernées par l'article que tu as envoyé sauf les affiches sur les panneaux électoraux, là c'est interdit j'en suis sûr-e. Pour le reste, on peut coller par dessus, déchirer, alors pourquoi ne pourrait-on pas écrire ? 🤷
Si tu ne sais pas faire un garrot en temps voulu tu pourras toujours dire aux autres secouristes qui savent que tu passes après eux pour noter l'heure du garrot sur les avant-bras avec ton Posca ! 😉
Je l'ai vue en VOST. Le doublage français me fait peur. J'ai entendu des extraits et je suis pas convaincu-e. Après c'est difficile de mon convaincre en doublage.
