56 2025-01-23 23:55:16 5745 to previous larryv undid rev 55 (quotes are unnecessary around the word following `case`) view
55 2025-01-23 23:47:40 5751 to previous 81 Add quotes around variables view
54 2022-08-01 10:02:57 5745 to previous 89 fixed quoting, in "else printf ..." below "Bash version 3 and above have..." view
53 2022-04-19 05:23:33 5741 to previous emanuele6 clarify that that enabling the extglob shopt is not necessary to use extglob patterns inside of [[ in bash4.1 view
52 2022-04-19 05:17:39 5743 to previous emanuele6 remention shopt-sextglob, but add comment about shopt not being necessary in ksh. add syntax highlighting. echo -> printf. fix indentation. `{{{ a}}}' -> ` {{{a}}}' view
51 2022-04-19 04:14:49 5503 to previous emanuele6 remove "shopt -s extglob" from Bash/ksh example: shopt doesn't exist in ksh and is not necessary in bash. view
50 2020-10-15 10:20:40 5521 to previous StephaneChazelas   view
49 2020-10-15 10:17:02 5495 to previous StephaneChazelas several corrections. view
48 2016-02-28 14:27:15 4801 to previous izabera printf %f 0x10 returns 0 view
47 2016-02-06 03:08:22 4660 to previous larryv fixed typo view
46 2015-03-01 21:43:37 4659 to previous geirha bashfaq is brittle about empty lines view
45 2015-03-01 16:03:15 4661 to previous pdm-l03   view
44 2015-02-16 13:01:43 4174 to previous TripleEe Demonstrating how to combine cases in "case" view
43 2015-02-16 12:58:49 3981 to previous TripleEe Second "case" also demonstrates disallowing multiple decimal points view
42 2015-02-16 12:51:56 3893 to previous TripleEe In case statement, you can trim any prefix sign; fix a couple of minor formatting errors view
41 2015-01-12 10:10:09 3514 to previous geirha = rather than ==, for consistency view
40 2015-01-12 00:55:54 3515 to previous GreyCat The proposed change is incorrect. view
39 2015-01-11 22:54:10 3513 to previous 112   view
38 2014-05-04 22:03:53 3515 to previous ormaaj oops view
37 2014-05-04 22:01:39 3453 to previous ormaaj Adding the case of a bare +/- or empty doesn't complicate things much (I think). Needs testing. view
36 2014-05-02 14:28:21 3574 to previous ormaaj Fix some bugs. ksh has always supported [[. rm'd example. =~ shouldn't be shunned due to bash 3's bad implementation. rm'd (again). =~ (and [[) will quite likely be POSIX at some point. view
35 2014-05-02 13:25:28 4036 to previous ormaaj POSIX doesn't require %f. Some shells printf(1) (ksh/zsh) evaluate arithmetic. Unlike C varargs functions (like printf), they may perform implicit conversion to float successfully. view
34 2013-08-17 22:52:06 3995 to previous 187 Remove crappy (("$foo")) suggestion. See: http://sprunge.us/BThD view
33 2012-12-02 11:27:59 4276 to previous geirha toc broken again view
32 2012-12-02 02:34:38 4278 to previous S01060048548a70fe   view
31 2012-10-24 17:34:14 4015 to previous ormaaj rm the entire "declare -i" section with dangerous examples. declare -i is NOT a method of testing for valid integers. It requires extra care - not recommended for beginners. view
30 2012-05-11 20:51:25 5804 to previous e36freak typo correction, incorrect variable name view
29 2012-04-04 22:41:19 5801 to previous GreyCat "Using eq" was already in the page. Add that phrase to the section header for emphasis. view
28 2012-04-04 12:28:37 5955 to previous GrzegorzRumatowski eq method added view
27 2012-04-04 11:51:59 5785 to previous Lhunath The eq operator is covered by the [ and printf section. view
26 2012-04-04 11:48:57 5846 to previous oberon-i eq method added view
25 2011-10-04 06:59:36 5785 to previous dialup-4 one RE does it all view
24 2011-06-29 14:24:47 6034 to previous irc2samus if you're validating it's more natural to have the desired outcome on the "true" part of the if block view
23 2011-04-11 21:16:06 6033 to previous 109   view
22 2010-02-24 14:48:18 6033 to previous kurkale6ka The second star IS actually needed, otherwise a pattern like test1234 would fail view
21 2010-02-24 14:07:50 6029 to previous webgw1 The second star isn't needed view
20 2010-02-24 14:03:45 6032 to previous webgw1 The second star isn't needed view
19 2010-01-15 23:59:45 6033 to previous GreyCat restore some deleted content; clean up the previous "clean-up" view
18 2010-01-15 20:30:25 5228 to previous ppp089210037022 a bit of clean, add the solutions using [ and printf view
17 2008-11-22 21:55:28 6058 to previous GreyCat first-line view
16 2008-11-22 14:08:29 6060 to previous localhost converted to 1.6 markup view
15 2008-06-14 01:39:12 6054 to previous GreyCat   view
14 2008-06-13 18:51:30 6054 to previous 74-140-161-210 mention read's arithmetic evaluation view
13 2008-05-02 12:55:51 5780 to previous GreyCat clean up (including the ridiculous error in the almighty xmb's example) view
12 2008-05-02 11:03:52 5644 to previous 194 added shopt -s extglob view
11 2008-03-06 14:13:49 5498 to previous GreyCat expand on "declare integer" view
10 2008-03-06 04:59:38 4676 to previous pgas move the declare -i stuff down as it is a bit different, change the examples view
9 2008-03-06 04:51:54 4550 to previous pgas a word about arithmetic with declare -i view
8 2008-03-05 21:43:20 4430 to previous cpe-74-65-28-251 Made mention of the integer attribute for variables view
7 2007-07-30 13:36:51 4055 to previous GreyCat move that extglob solution up above the regex ones; add a ksh-based one too; clean up a lot view
6 2007-07-28 04:53:56 2698 to previous ppp020-014 add matching with extglob view
5 2007-07-13 15:39:25 2537 to previous GreyCat screw it. put the egrep one FIRST, because it actually works. insert warnings. leave the bash ones in, after the warnings. view
4 2007-07-13 15:33:11 2260 to previous GreyCat gods, what a fucking mess. view
3 2007-07-11 22:25:22 1554 to previous cpe-74-65-28-251 Fixed broken escaping view
2 2007-05-07 18:02:07 1556 to previous GreyCat [0-9]* before the decimal, not [0-9]+, so we can have .5 as a number. This requires checking non-blank-ness. view
1 2007-05-02 23:46:43 1429 redondos   view
