III. Bash

following are bash specific

Explorer Windows File System (so helpful connecting sub-system partition to main OS) open windows file explorer GUI for WSL

explorer.exe .
How to echo or cat write to a file with Bash:
cat >> /path/to/existingFile.text<< EOF
some text line 1
some text line 2
some text line 3
EOF

switch cat >> to cat > to create a file instead of append

cat > /path/to/newFile.text<< EOF
some text line 1
some text line 2
some text line 3
EOF

(( expression )) <– this will execute/perform an expression

print BASH env

printenv

echo variables (example how to access vars in BASH)

echo $LANG # <-- LANG env var (bash)

$RANDOM in BASH will create a random number

echo $RANDOM # <-- 22024 : between 0 and 32767
I=0 # <-- passing this in the terminal will persist a var
(( I++ )) # <-- I will now become 1 and persist
# we don't need to prepend $ for vars in (( expression ))

this will print expressions for (( expression )) operations

help let
View file "long" with permissions list
ls -l

-rw-r--r-- in front of the file indicates the permissions: r = read, w = write, x = execute output: -rwxr-xr-x <– see x by 3 different “users” (all users can execute now)

Give executable permissions to a file
chmod +x filename.whatever

man command is “manual” (like help)

man bash # <-- prints manual for bash
man sleep # <-- prints manual for sleep (binary)

-e flag needed for special characters

echo -e "\n~~ Countdown Timer ~~\n"

lists root of the file system

ls /

ls /bin will list all binaries on the file system. Bash lives here: #!/bin/bash which will use bash commands. we can access other binaries or libraries here

lists bash commands

help

things we can pass to the bash TEST command (for testing true/false (for ifs or [[ EXPRESSIONS ]]))

help test
( expression ) # <-- evaluates expression/returns value
help [[ expression ]] # <-- output below
  ( EXPRESSION )    Returns the value of EXPRESSION
  ! EXPRESSION              True if EXPRESSION is false; else false
  EXPR1 && EXPR2    True if both EXPR1 and EXPR2 are true; else false
  EXPR1 || EXPR2    True if either EXPR1 or EXPR2 is true; else false

When the `==' and `!=' operators are used, the string to the right of
the operator is used as a pattern and pattern matching is performed.
When the `=~' operator is used, the string to the right of the operator
is matched as a regular expression.

The && and || operators do not evaluate EXPR2 if EXPR1 is sufficient to
determine the expression's value.

Exit Status:
Returns success if EXPR evaluates to true; fails if EXPR evaluates to
false or an invalid argument is given.

we can evaluate any expression in the BASH terminal or .sh script:

[[ 4 -le 5 ]] # <-- `-le` === less-than-or-equal

echo $?

echo $? # <-- prints last bash command's EXIT STATUS
0 # <-- 0 === true (0 === no errors)

[[ 4 -ge 5 ]]
echo $?
1 # <-- 1 === false (> 0 === contains errors | "false")
[[ 4 -ge 5 ]]; echo $? # <-- run multiple comands on single line with `;`
1 # <-- output

we can think of 0 return as TRUE but it actually means command had 0 errors (EXIT STATUS)

check if a file exists (and output EXIT STATUS) -a | -e THIS WILL CHECK THE FOLDER FROM WHERE THE COMMAND WAS ENTERED

[[ -a countdown.sh  ]]; echo $?
0 # <-- output 0 if file exists

to list all variables in BASH

declare -p

all variables: @ | *

ARR=("a" "b" "c")
echo ${ARR[@]}

declare -p ARR
# --> declare -a ARR=([0]="a" [1]="b" [2]="c")
# --> -a === array

Read (capture user INPUT)

capture user input

read

Return IP address of Windows Machine as seen from WSL VM

ip route show | grep -i default | awk '{ print $3}'

Debugging in Bash

set -x at the top of a script enables debugging (printing executed commands to the terminal)

#!/bin/bash

set -x

# Your script goes here

IV. Powershell

get current path

(Get-Item .).FullName

pipe to clipboard

(Get-Item .).FullName | Set-Clipboard

& call operator

& notepad.exe
& calc.exe

& "C:\Path\To\SomeExecutable.exe"

run single cmd prompt command in pshell

cmd /c <command>
// e.g.
cmd /c dir // like ls
cmd /c set # displays your system env
cmd /c set > file_name.txt // like cat

list all running processes w/ binary program names

netstat -ba # will require elevated perm
netstat -ban # this will also show IPs

get powershell version

$PSVersionTable.PSVersion

open persistent PS profile file will create new $PROFILE if not exists

code $PROFILE.AllUsersAllHosts

put this inside your $PROFILE.ps1 opens specified dir on shell launch

Set-Location C:\Users\User\Dev

to Set-Alias that takes params

function ListAll { # script block/fn
    Get-ChildItem -Force
}

Set-Alias ls-a ListAll # create Alias/invoke
# Set-Alias -Name list -Value cmdlet/fn

XIV. Git

tagging commits, usually for release

git tag -l # the -l (list) flag is opt
# lists all current tags
git tag v1.0.0 2261e84e
# tags a commit by sha
git tag v1.0.1
# tags your current commit
git tag -a v1.0.2 -m "annotate this tag"
# -a flag for annotate -m for message

git show v1.0.0
# this will show associated commit

git log --pretty=oneline
# shows all commits pretty

git push origin --tags
# this will push all tags that aren't already on the remote up

using the git stash stack

git stash # puts all workind dir changes on top of stash stack
git stash apply # brings back that level of the stack into working dir (un staged)
git stash pop # same as apply except "pops" that level off the stack (dropping it)
git stash drop # removes the top level of the stack
git stash list # shows the entire stack, the newest is always the lowest number

git stash -u # same as git stash --include-untracked
# will include more than just modified and staged
git stash --all # similar to -u ?

git stash --patch # stash hunk at a time

git status

git status -s # short output

if you have changes on your remote that you didn't mean to track: add dir and/or files to .gitignore then use this command to remove from the index (the actual location in <baseOfRepo>/.git/index which is your staging area)

git rm --cached put/here/your/file.ext # for files
git rm --cached folder/\* # for directory of files
# append --dry-run # to see what will happen w/o executing
git push ... # to update removal and untrack to remote

CAUTION: i have only used this on auto-generated files, so i safely know they will be recreated locally upon deletion... proceed with caution by backing up files if this is not the case for you...

bring committed changes back to working directory (e.g. for committed files you want to stash that have not been pushed

git reset HEAD~1 --soft

probably best reset option. discard 2 of 3 git areas

git reset --mixed
# discards commit and staged changes (in the git index) but KEEPS changes in your working dir (files in IDE)

show remote repo branches state compared with local branches

# git remote show <remote alias>
git remote show origin

git add --patch "hunks"

git add -p # shows hunks diff in CLI

tool for giff from all commits on current branch

gitk --all

switch to FILE and discard changes (destructive)

git restore

move between branches (replaces checkout) doesn't discard changes

git switch # only takes branch as arg
# checkout is for switching tags and commits

Rebase

how to proceed in interactive rebase

# git rebase -i or something
# once you decide the strategy for rebasing (specific files squash, pick, reword, etc)
# then how to continue after handling merge conflicts and whatnot
git add README.txt && git rebase --continue
