* Notes
** why
- there are many tools that make life easier for programmers
- lecture notes and recordings are available online
** the shell
- programs are meant to be integrates with each other through the shell
- most common shell is Bourne Again Shell (bash)
** shell prompt
- typical shell prompt:
#+attr_html: :width 300px
file:../_share/media/img/lecture01/ex01.png
- shells can be customized extensibly
- arguments are seperated by whitespace
- multiple words can be passed as a single argument via:
- quotes
#+begin_src bash
echo "Hello world"
#+end_src
- escapes
#+begin_src bash
echo Hello\ world
#+end_src
** how does the shell know where programs are
- via environment variable
- things that are set whenever you start your shell
- where is your home directory
- what is your username
- what are the PATHs to your programs
- shells, and bash in particular, are programming languages
** paths
*** PATH environment variable
- a list seperated by colons (:)
- when bash is asked to run a program bash will search through the directories in path until it finds the program
*** absolute vs relative path
- pwd: print working directory
- all relative paths are relative to your current working directory
- absolute path starts with '/'
*** special directories
- '.' current directory
- '..' parent directory
*** tilde (~)
- always expands to your home directory
*** dash (-)
- toggles to the previous directory you were at
#+begin_src bash
cd /home/ronny/programs/notes/courses
cd ../../
cd -
pwd
#+end_src
the output will be
=/home/ronny/programs/notes/courses=
** permissions
*** groups of three
- read
- write
- execute
*** directories
- read: are you allowed to see the files
- write: can you rename the files in the directory
- execute: "search" are you allowed to enter this directory
- to access a file in a directory, you need execute permissions on all directories in the path
** piping
- every program has two streams
- input stream
- output stream
- shell allows you to change streams
- angle brackets
- left angle < : rewire input
- right angle > : rewire output
- example
#+begin_src bash
echo hello > hello.txt
cat < hello.txt
#+end_src

* Notes
** bash
*** spaces are critical with bash
- this works:
#+begin_src bash
foo=bar
echo $foo
#+end_src
- this doesn't:
#+begin_src bash
foo = bar
echo $foo
#+end_src
- the output of that will be
=zsh: command not found: foo=
- what happens in the above example is that we are effectively calling the "foo" program with the arguments: "=" and "bar"
*** quotes
- you can use double or single quotes to print a value
#+begin_src bash
echo "Hello"
#+end_src
#+begin_src bash
echo 'Hello'
#+end_src
- double quotes can interpolate variables
#+begin_src bash
echo "Value is $foo"
#+end_src
will return: =Value is bar=
- single quotes can NOT interpoloate variables
#+begin_src bash
echo 'Value is $foo'
#+end_src
will return: =Value is $foo=
** sequential execution
*** bash functions
- mcd.sh
#+begin_src bash
mcd() {
mkdir -p "$1"
cd "$1"
}
#+end_src bash
- creates a function that can be executed after loading
- $1 is a global variable referring to the first parameter
*** source
- using source mcd.sh
=source mcd.sh=
- then carry out the function
=mcd testdir=
- this will create a new directory and cd into it as per the definied functioned
** error codes
*** commands to access codes or values
- $0 -- name of the script we are currently in
- if you run this in the shell it will display 'bash'
- $1->$9 -- the first through ninth argument given to a script
- $? -- the last error message
- $_ --- last argument of the previous call
- !! -- recreates the last call with it's arguments
- use with sudo if you found your call needed a sudo and you don't feel like retyping it again
#+begin_src bash
ls -lah
sudo !!
#+end_src
*** code values
- boolean
- true returns an error code of 0
- false returns an error code of 1
** using $@ and $*
- represents all the arguments passed to a script or a function as separate, individual strings. It preserves each argument as a distinct item, even if the argument contains spaces.
*** key points about $@
1. All Arguments: It refers to all the command-line arguments passed to the script.
2. Preserves Spaces: If an argument contains spaces, it is treated as a single argument.
3. Usage: It is commonly used in a loop to iterate over each argument.
*** example
#+begin_src bash
./myscript.sh file1.txt "file with spaces.txt" file3.txt
#+end_src
then $@ will be
=file1.txt "file with spaces.txt" file3.txt=
*** differences between $*
- *$@* treats each argument as a sepearte item
- *$** treats all arguments as a single, combined string
** logical operators
- you can use the error return value in conditionals
*** example using the OR conditional
#+begin_src bash
false || echo "Oops fail"
"Oops fail"
#+end_src
*** example using the AND conditional
#+begin_src bash
true && echo "this will print"
"this will print"
#+end_src
** concatenate commands
- you caoncatinate commands using the semicolon: *;*
#+begin_src bash
false; echo "this prints always"
"this prints always"
#+end_src
** common substitution
- take the output of a command and put it in a variable
#+begin_src bash
foo=$(pwd)
echo $foo
"/Users/ronny/..."
#+end_src
- this can also be done by placing that format in a string and it will expand the string
#+begin_src bash
echo "the pwd output is: $(pwd)"
"the pwd output is: /Users/ronny/..."
#+end_src
** process substitution
*** description
Bash process substitution is a feature that allows you to use the output of a command or a process as if it were a file. It enables you to redirect input or output between processes in a flexible way without needing intermediate temporary files.
*** Syntax
- creates a temporary file descriptor for the output of the command, which can be used as an input file in another command.
#+begin_src bash
<(command)
#+end_src
- creates a temporary file descriptor for writing to the command, which can be used as an output file in another command.
#+begin_src bash
>(command)
#+end_src
*** examples
- this will take b, a, d, c and sort it so the result is 'a, b, c, d'
#+begin_src bash
sort <(echo -e "b\na") <(echo -e "d\nc")
#+end_src
- this will list the files, send the list to *tee* which will split a portion off to the screen and the rest to grep, followed by text_files.txt
#+begin_src bash
ls | tee >(grep "txt" > text_files.txt)
#+end_src
#+begin_src bash
echo "Starting program at $(date)" # Date will be substituted
echo "Running program $0 with $# arguments with pid $$"
for file in "$@"; do
grep foobar "$file" > /dev/null 2> /dev/null
# when pattern is not found, grep has exit status 1
# we redirect STDOUT and STDERR to a null register since we do not care about them
if [[ "$?" - ne 0 ]]; then
echo "File $file does not have any foober adding one"
echo "# foobar" >> "$file"
fi
done
#+end_src
- *$$* pid given for program
- *$#* number of arguments
- *$@* expands to all the arguments
- can be used in a for loop
- *2>* refers to STDERR
- *>* refers to STDOUT
** test utility
test is a bash utility that you can use to test the condition of a file. look at the man page for more info
** curly braces
curly braces are used as a form of program command expansion.
the braces contain a number of arguments seperated by commans that will expand into arguments for the program
*** example
#+begin_src bash
touch foo{,1,2,10}
touch foo foo1 foo2 foo10
cp foo{,.old}
cp foo foo.old
#+end_src
*** ranges
this takes the format {1..20}
#+begin_src bash
touch directory{1..4}/foo{a..z}.txt
#+end_src
** python scripts
*** making them bash executable
- reference the python compiler at the top of the file
- do it directly:
#+begin_src bash
#!/usr/local/bin/python
#+end_src
- use the env program to do so
#+begin_src bash
#!/usr/bin/env python
#+end_src
*** args can be found through sys.argv[1:]
#+begin_src python
import sys
for arg in reversed(sys.argv[1:]):
print(arg)
#+end_src
** checking for problems in bash scripts using 'shellcheck'
#+begin_src bash
shellcheck some_bash_script.sh
#+end_src
- will tell you problems
- and warnings
** man command
- works with both os, and installed tools
- 'tldr' is easier to read
** find
