Project:Branches: galelo04/rtems:shell-add-support-for-head-command to rtems/rtos/rtems:main Author: Mostafa Abdelglel ## Summary shell: Port the head command from FreeBSD - port the head command from the FreeBSD source code - port expand_number() to support SI suffixes - port getline() from NetBSD ( #define _GNU_SOURCE didn't work ) - add necessary build support verification: verified manually on the sparc-rtems7-sis simulator. I adapted some of the test cases from the FreeBSD test suite (tests/head_test.sh) and verified the output matches the host head command. - default no options: head file (10 lines). - line count: head -n 5 file. - byte count: head -c 5 file - SI units: head -n 1k file - multiple files: head file1 file2 (verified that it produces headers without the -q flag) - verbose flag: head -v file - illegal line count: head -n fj file - missing line count: head -n file references: - [FreeBSD head source code](https://github.com/freebsd/freebsd-src/blob/main/usr.bin/head/head.c) - [FreeBSD head test suite](https://github.com/freebsd/freebsd-src/blob/main/usr.bin/head/tests/head_test.sh) - [FreeBSD expand_number() source code](https://github.com/freebsd/freebsd-src/blob/main/lib/libutil/expand_number.c) - [NetBSD getline() source code](https://github.com/lattera/freebsd/blob/master/contrib/file/getline.c) ## Generative AI <!--Default settings, if it is a dropdown it will set after submission--> -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/merge_requests/1061 You're receiving this email because of your account on gitlab.rtems.org.
