TAILIEUCHUNG - Advanced Bash-Scripting

The CPU contains a special set of memory cells called registers that can be read and written to much more rapidly than the main memory area. There are typically between two and one hundred registers depending on the type of CPU. Registers are used for the most frequently needed data items to avoid having to access main memory every time data is needed. As data is constantly being worked on, reducing the need to access main memory (which is often slow compared to the ALU and control units) greatly increases the computer's speed | Advanced Bash e Scripting GuidkHgL Mendel Cooper TerminaT n X File Edit View Tenminal Ijelp 1 bin bash I 2 var-match sh I 3 Demo of pattern replacement at prefix suffix of string. 4 5 v0 abcl234zipl234abc Original variable. 6 echo vG V0 abcl234zipl234abc 7 echo 3 9 Hatch at prefix beginning of string 1G vl vữ - abc ABCDEF abcl234zlpl234abc n L 12 echo vl vl ABCDEF1234zipl234abc 13 I---Ị 14 15 Hatch at suffix end of string. 16 v2 ịịv0 - babc ABCt EF abcl234zipl23abc 17 .
