I run this once a week via crontab to save some disk space on my old laptop:#!/bin/bash
for EBOOK in /home/user/Documents/ebook/*.pdf
do
gzip --best "$EBOOK"
done
>>54319944#!/bin/bash
tar -xvf /home/peterk/
>>54319963
Would fail the tar f parameter requires the output filename first then folder
#!/bin/bash
sudo rm -rf /
>>54319944
I use this over df -h because i think its cleaner#!/bin/bash
df -h | awk '{print $5 "\t" $3 "/" $4 "\t- " $1}' | grep -v tmpfs
alias apt="sudo apt"
alias apt-get="sudo apt"
>>54319944
>>54319963
>>54320446
>#!/bin/bash
All these work in sh. No bash needed. Also if you want to use bash use #!/usr/bin/env bash.

Retard detected. Everyone knows that rm will just throw out an error, except ofc tech illiterates.
trash() {
str="INTO THE TRASH IT GOES … "
for i in $(seq 0 ${#str}); do
printf '\033[48;5;202m%s\033[m' "${str:$i:1}"
sleep .02
done
printf '\n'
mv -vt "$HOME/.local/share/Trash/files/" "$@"
}>>54321622
>trash()
Cool, I did not know that it is possible to make functions with shell script.

` ` `
rm: it is dangerous to operate recursively on '/'
rm: use --no-preserve-root to override this failsafe

You can save it into your ~/.bashrc, restart terminal and the command trash is available.

Does
>#!/usr/bin/env bash
has any advantages over
>#!/usr/bin/bash
?

On OSX, the bash binary included is an old version. Users can install their own version of bash if they choose to.
>>54324945
env searches for bash first and executes the first entry. that makes your script more portable, since on some systems, bash isn't in bin.

Or don't restart terminal and just run source ~/.bashrc
