Public bug reported: This bug is not related to any GUI, but discovered while logged into ubuntu/linux using Putty. Here is the version:
Welcome to Ubuntu 24.04.1 LTS (GNU/Linux 6.8.0-48-generic x86_64) The bug is that /bin/csh can no longer wild card more than 98 items. If you try it, /bin/csh crashes with a Segmentation Fault (core dump). apt-cache policy csh csh: Installed: 20230828-1 Candidate: 20230828-1 Version table: *** 20230828-1 500 500 http://archive.ubuntu.com/ubuntu noble/universe amd64 Packages 100 /var/lib/dpkg/status Here is a test: Create two directories, /tmp/test98 and /tmp/test99. In /tmp/test98, place 98 files of any name or size In /tmp/test99, place 99 files of any name or size swimdev3-mark[18]: cd /tmp/test98 swimdev3-mark[19]: /bin/ls -F 01 06 11 16 21 26 31 36 41 46 51 56 61 66 71 76 81 86 91 96 02 07 12 17 22 27 32 37 42 47 52 57 62 67 72 77 82 87 92 97 03 08 13 18 23 28 33 38 43 48 53 58 63 68 73 78 83 88 93 98 04 09 14 19 24 29 34 39 44 49 54 59 64 69 74 79 84 89 94 05 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 swimdev3-mark[20]: /bin/ls -F * 01 06 11 16 21 26 31 36 41 46 51 56 61 66 71 76 81 86 91 96 02 07 12 17 22 27 32 37 42 47 52 57 62 67 72 77 82 87 92 97 03 08 13 18 23 28 33 38 43 48 53 58 63 68 73 78 83 88 93 98 04 09 14 19 24 29 34 39 44 49 54 59 64 69 74 79 84 89 94 05 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 swimdev3-mark[21]: cd /tmp/test99 swimdev3-mark[22]: /bin/ls -F 01 06 11 16 21 26 31 36 41 46 51 56 61 66 71 76 81 86 91 96 02 07 12 17 22 27 32 37 42 47 52 57 62 67 72 77 82 87 92 97 03 08 13 18 23 28 33 38 43 48 53 58 63 68 73 78 83 88 93 98 04 09 14 19 24 29 34 39 44 49 54 59 64 69 74 79 84 89 94 99 05 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90 95 swimdev3-mark[23]: /bin/ls -F * Segmentation fault (core dumped) /tmp/test98 has 98 files in it. I can wildcard with “*” and it returns all the files as it should. /tmp/test99 has 99 files. If I try “ls -F *” it core dumps. Note that without the -F flag, ls works and returns the file names. But with the -F flag it crashes. I believe the bug is in /bin/csh, not “ls” or other programs. If you were to try: cd /tmp/test99 foreach i (*) /bin/csh will crash and the putty window will disappear. You don't even have to create the /tmp files above to test this -- any directory with more than 98 files will trigger the crash. E.g.,: swimdev3-mark[24]: /bin/ls -F /usr/bin/* Segmentation fault (core dumped) Or if you want to test foreach without having the putty window crash and disappear, start a new /bin/csh and try it: swimdev3-mark[25]: /bin/csh swimdev3-mark[1]: foreach i (/usr/bin/*) Segmentation fault (core dumped) swimdev3-mark[26]: This only happens in /bin/csh. sh and bash do not exhibit this bug. I have another linux server that has an older version of ubuntu: Welcome to Ubuntu 20.04.1 LTS (GNU/Linux 5.4.0-166-generic x86_64) But 20.04.1 does not have this bug. But the latest ubuntu (24.04) does.
