I need some help understanding this bash script - Ask Ubuntu

i've been googling each parameter etc in script trying understand each line saying (if makes sense). wondered if kind enough me out helping me 'translate' plain english means? i've done first 5 lines i'm not sure if it's correct :/ appreciated. thank you!

this script:

#!/bin/bash current=0 while [ $seconds -le 10 ];     if [ $seconds -eq ${current} ];         echo ${current}         current=$((${current}+1))     fi done 

the magic of built-in bash variable $seconds

your script highlights built-in bash variable $seconds keeps track of how many seconds bash script has been running. starts @ 0 , working variable current set value @ beginning of script. script loops , increments current each time $seconds changes , displays "1, 2, 3... 10" on screen.

---

analyzing bash script line line:

#!/bin/bash tells system bash script

current=0 sets variable current 0

while [ $seconds -le 10 ]; do when number of seconds script has been running less or equal 10 following

if [ $seconds -eq ${current} ]; then if value of current equal number of seconds then:

echo ${current} display current value (0 initially, 1, 2, 3... 10)

current=$((${current}+1)) increment current value

fi end of if statement, required syntax rules

done end of while loop, required syntax rules

testing script

to test script copy , paste op's text new file. our purposes call file seconds. mark file executable command:

chmod +x seconds 

then call bash script current directory prefix in front:

./seconds
