Bash Scripting for Starters (Like me)

• For Loops
• If else conditionals
• [..] vs [[..]]
• Debugging (sort of) Bash Programs (Tracing the execution)
• Defining Functions
• The function definition must precede the first call to it. There is no method of "declaring" the function, as, for example, in C.
• About "returning values" from a bash function
• Mentions the use of global variables
• Command substitution
• Specific Commands
• Using grep in bash
• egrep (extended grep)
• Directory Stack: dirs, pushd, popd
• File test operators ('Is this a directory?', 'Does this file exist?'..etc.)

Miscellaneous

• There's no function 'declaration'. The function definition must precede the first call to it.
• All variables are global by default, unless specified otherwise.
