tail -n +2 someFile
*Notes: You MUST include the + sign or else the last 2 lines will be printed instead.
To remove N lines from the start of the file
tail -n +$M someFile
*NOTES: M = N + 1
You MUST include the + sign in-front of the number M or else the output will be the last M lines instead.
for i in $(seq $START $STEP $END); do echo "Iteration $i"; someCommand; someOtherCommand ; done
*INFO: $START: The starting value for the for loop, can be replaced by an integer.
$STEP: The step that the for loop is performing at the end of each iteration, can be replaced by an integer.
$END: The ending value for the for loop, can be replaced by an integer.

find $LOCATION -name "$FILENAME" -exec somecommand '{}' \;
The above command will search in $LOCATION for all files named $FILENAME and apply the command that you define at somecommand.
The argument ‘{}’ inserts each file found into the somecommand syntax. The \; argument indicates the exec command line has ended — YOU MUST INCLUDE IT.
du -sh someName
*INFO: someName can be replaced by any folder or file name or even a regular expression (for example to get the size of all txt files you need to invoke du -sh *.txt)
By using the parameter -s (which stands for summarize) you will get back only the total size in bytes.
By using the parameter -h (which stands for human readable format), for any size output you will get it back in Kilobytes, Megabytes etc.
