What I want to achieve is to automatically install NPM packages, so I created a separate variable which holds "sudo npm install" and iterating over an array which has the package name.
Facing error that command not found but if I put it into the console it works.
npm_base='sudo npm install '
npm_scripts=("-g eslint")
for element in ${npm_scripts[@]}
do
${npm_base}${element}
done
How can I increment a variable assigning its value to PROMPT_COMMAND variable?
Inside .bashrc I created variable a and assigned value to 0
and then added this
a=0
PROMPT_COMMAND=`((a++))`
When I echo PROMPT_COMMAND it shows that it is empty.
I want to save the result of the $SECONDS command into a variable, to print time in format HH:MM:SS.
This is what I've tried so far. I tried to print it in different ways and was always getting the result as 0:
time_spent="$SECONDS"
echo "Time: $time_spent"
I want to print time spent in the shell when I close my console. I created a script that runs every time the console was closed.
I wanted to know if there is any command or any other way I can check my command history only in the current session.
