String Manipulations
- To replace all substrings by another, use the following syntax:
echo ${stringZ//abc/xyz}
This would replace all occurences of abc in stringZ by xyz. The following replaces only the first match:
echo ${stringZ/abc/xyz}
Special Symbols
- "$@" expands to all command-line parameters.
Command Line Utilities
- sdiff -s will generate a formatted output of the differences between two files. Very useful.
