GNU Parallel in Bash optimizes task execution by leveraging multiple CPU cores for simultaneous job processing, enhancing speed and productivity. It handles task distribution automatically across available cores, continuing allocation as cores free up. Installable via most Linux repositories, it simplifies shell command execution. For instance, counting lines in text files or converting image formats can be efficiently processed with simple commands like `ls *.txt | parallel wc -l` or `ls *.png | parallel convert {} {.}.jpg`. Scripts, like resizing images in parallel, demonstrate its potential to significantly reduce processing times, making it invaluable for efficient computational task management.

Precompiling regex patterns in `awk` and `sed` enhances script efficiency when processing text in Linux. `awk` allows regex to be defined once, reducing reevaluation, while `sed`, lacking native precompilation, uses shell variables for similar gains. This approach improves both performance and script maintainability.

In Linux Bash scripting, using subshells inside loops can decrease performance due to the high resource usage of spawning new subshells in each iteration. Process substitution, which uses `(commands)`, serves as an efficient alternative, allowing direct interaction with processes as if dealing with files. This method enhances script efficiency, especially when handling large datasets or in extensive loops, avoiding the overhead brought by subshells and improving execution speed.
