Simple and Stupid Bash Script Library

kissbash - A Simple and Stupid Bash Script Library

Despite what people say, I decide to write a bash script library.

If nobody cares, at least it will benefit myself.

How to use

Set the KISSBASH_PATH environment variable and you are good to go.

$ git clone https://github.com/yyu/kissbash.git ~/.kissbash
$ export KISSBASH_PATH=~/.kissbash/kissbash

Example

$ cat > /tmp/myscript << "EOF"
. "$KISSBASH_PATH/console/lines"
echos 3; echo line1
echo line2 | line_pre_echo_control up1 up1 up1
echo line3
echos 10
cat /tmp/myscript | line_pre_echo_control up1 up1
echos 7
EOF

output:

$ bash4 /tmp/myscript

line2
line3
line1

echos 7
cat /tmp/myscript | line_pre_echo_control up1 up1
echos 10
echo line3
echo line2 | line_pre_echo_control up1 up1 up1
echos 3; echo line1
. "$KISSBASH_PATH/console/lines"

$

Document

console/lines

echos

One argument:

$ . $KISSBASH_PATH/console/lines
$ (echos 2; echo hello) | cat -n
     1	
     2	
     3	hello

More than one argument:

$ . $KISSBASH_PATH/console/lines
$ (echos 3 .; echo hello) | cat -n
     1	...hello

serr_with_color

$ . $KISSBASH_PATH/console/lines
$ echo hello | serr_with_color red
hello

You should see red hello in your console.

tee_serr_with_color

$ . $KISSBASH_PATH/console/lines
$ echo hello | tee_serr_with_color red
hello
hello
$ echo hello | tee_serr_with_color red > /dev/null
hello

You should see red hello for stderr and normal hello for stdout.

line_pre_echo_control

$ . $KISSBASH_PATH/console/lines
$ echo -e "\none\n"; echo two; echo three

one

two
three
$ echo -e "\none\n"; echo two | line_pre_echo_control up1; echo three

one
two
three

exec/explicitly

$ . $KISSBASH_PATH/exec/explicitly
$ explicitly echo "2+3" | bc
echo 2+3
5
