The main function execSteps executes emerge --pretend $package one by one, and these package's names(only names, no version information) are stored in a text file stepFile. Some of packages may have extra need for configuring package.use, package.license, this kind of extra information will be shown up after executed emerge --pretend $package. The second while loop in main function and function acceptPKGTypeItems are intended to deal with this kind of extra information.
When emerging one particular package, it may depend on a couple of more packages. For example, emerge --pretend ceph, I need to emerge more than 10 packages before ceph gets emerged. Along with Gentoo/Linux updated, new version of package may be applied. So text file stepFile only contained with package names which I need, and parsing the result of emerge --pretend $package, I'm able to get updated package emerged.
At case 0), this while loop is intended to parse the result of emerge --pretend $line(which is from stepFile), for example emerge --pretend ceph and get its dependant packages with current version, for example dev-libs/boost-1.57.0, pass it as an argument to function emgRecursion because dependant package dev-libs/boost-1.57.0 of package ceph may have its own dependant packages which are dev-libs/boost-build-1.57.0 and dev-libs/boost-1.57.0.
My problem is I get an error while : command not found in function emgRecursion when I enter 0 at case 0). Is it another different shell thing? I've added a pair parenthesis between the second while loop in main function which helped get readin answer from user for choosing package.use, package.license, or package.keywords. And I've tried to add another pair of parenthesis between the third while loop, the same problem. I've tested emgRecursion and acceptPKGTypeItems separately, both of them work fine and correctly.
Any ideas? Thank you very much.
