bashful – Invoke bash commands from within LaTeX

The pack­age makes it pos­si­ble to ex­e­cute Unix bash shell scripts from within LaTeX. The main ap­pli­ca­tion is in writ­ing com­puter-sci­ence texts, in which you want to make sure the pro­grams listed in the doc­u­ment are ex­e­cuted di­rectly from the in­put. The pack­age may use other Unix shells than bash, but does not work with­out mod­i­fi­ca­tion in a Win­dows en­vi­ron­ment.
The pack­age re­quires the -shell-es­cape flag when LaTeX is pro­cess­ing your doc­u­ment.
