My Linux stuff: commands, alias, etc

Just some Linux commands, scripts, references that I use

---

1. Linux alias

2. My tools and scripts

   • ngrok

3. CopyQ: Clipboard manager (https://hluk.github.io/CopyQ/)

Alias

I have several Linux alias, some of them are "temporal" (defined for an ongoing project) and others are "permanent".

All my alias are defined in a file myalias and I call this file from .profile script

To avoid a collition with Linux commands or aliases I prefer to use UPPERCASE for mine (my convention ¯_(ツ)_/¯):

Some examples and outputs:

# "permanent" alias

alias CA='conda activate $@'
alias CD='conda deactivate'
alias CL='ls -1d /sw/anaconda/envs/* | awk -F"/" "{printf(\"%-20s %s\\n\", \$5, \$0)}" | sort'

alias LA='alias | grep "^alias [A-Z]" | sed -e "s/^alias //" | sort | awk -F= "{printf \"%-10s %s\n\", \$1, \$2}"'

# "temporal alias"
# For project "RMC"

alias RMC='cd /projects/RMC/src'

Listing existing conda envs

$> CL
aws                  /sw/anaconda/envs/aws
cvtool               /sw/anaconda/envs/cvtool
guis                 /sw/anaconda/envs/guis

Listing existing alias

$> LA
AI         'cd /projects/ML/OPENAI; conda activate oai'
AID        'cd /projects/ML/OPENAI/vector-db'
CA         'conda activate $@'
CD         'conda deactivate'
CL         'ls -1d /sw/anaconda/envs/* | awk -F"/" "{printf(\"%-20s %s\\n\", \$5, \$0)}" | sort'
DF         'df -h |egrep -v "snap|tmpfs|boot|udev"'
DLC        'docker ps $@'
DLI        'docker image ls $@'
J          'jupyter notebook'
LA         'alias | grep "^alias [A-Z]" | sed -e "s/^alias //" | sort | awk -F
N          'nohup nautilus -w . > /dev/null 2>&1 &'
T          'touch .'
...

My Tools and scripts

I did some scripts and tools (I still doing, there is always an opportunity for a new script or tool in Linux)

My scripts and tools are in folder /sw (again my convention ¯_(ツ)_/¯), I found this convention useful: when I cange my computer I just copy this folder and run a script to "install all": generally, installation is is just define some environment variables and create some symbolic links

• ngrok

Sometimes I use ngrok to expose quickly a local port to internet (e.g.: testing a Flask or FasAPI development)

Script run_ngrok.sh is a wrapper to ngrok command

$> run_ngrok.sh -h
NAME
 Wrapper for ngrok command (https://ngrok.com/)

 ngrok command=/sw/ngrok

USAGE
 run_ngrok.sh [-P port_number] [-u user -p pass]  [-c http|tcp]

EXAMPLES
 run_ngrok.sh -P 8989                      # expose HTTP 8989
 run_ngrok.sh -P 8989 -u admin -p passw0rd # expose HTTP 8989 with basic auth admin:passw0rd
