由 烈酒焚心 提交于 2019-12-01 09:57:35
问题 I have a Cocoa application that need admin permission to execute a cmd, but in some extreme case like filename containing double quote, this code does not work.

get parent directory of a file in bash

由 眉间皱痕 提交于 2019-12-01 08:48:34
问题 How do I get a parent directory for a file? I want it to be safe on all kind of names: . .. path/to/my/file /absolute/path/to/my/file '-rf --no-preserve-root whatever'/test.zip (symbolic links) `'"`'{(}) I am more interested getting the canonical location on the file system than in traversing the path stated in the filename. Note that there are similar questions to this one, but none of them focuses on correctness, relative/absolute paths and "unsafe" names: [1] bash get the parent directory

printf field width doesn't support multibyte characters?

由 和自甴很熟 提交于 2019-12-01 08:02:58
问题 I want printf to recognize multi-byte characters when calculating the field width so that columns line up properly... I can't find an answer to this problem and was wondering if anyone here had any suggestions, or maybe a function/script that takes care of this problem. Here's a quick and dirty example: printf "## %5s %5s %5s ##\n## %5s %5s %5s ##\n" '' '*' '' '' "•" '' >## * ## >## • ## Obviously, I want the result: >## * ## >## • ## Any way to achieve this? 回答1: The best I can think of is:

How to subtract a year from a date stored in a variable in shell script?

由 巧了我就是萌 提交于 2019-12-01 07:51:49
问题 as_of_dt='2016-01-01' as_of_dt_prev_year=$($as_of_dt -d '-1 year' +'%Y-%m-%d') echo $as_of_dt_prev_year This does not work. error: -d: command not found However this works if we use '$date' instead of $as_of_dt. 回答1: Played around with it. This seems to work: as_of_dt='2016-01-01' as_of_dt_prev_year=$(date --date="${as_of_dt} -1 year" +'%Y-%m-%d') echo $as_of_dt_prev_year Note the double quotes that are needed for variable substitution to work. 来源： https://stackoverflow.com/questions/51259249

Find maximum positive integer value in Bourne Shell

由 我只是一个虾纸丫 提交于 2019-12-01 06:57:27
问题 I'm checking a counter in a loop to determine if it's larger than some maximum, if specified in an optional parameter. Since it's optional, I can either default the maximum to a special value or to the maximum possible integer. The first option would require an extra check at each iteration, so I'd like to instead find out what is the maximum integer that will work with the -gt Bourne Shell operation . 回答1: I'd stay clear of integer limits as they're non portable and problematic $ test

sourcing env output

由 蓝咒 提交于 2019-12-01 05:32:10
I have some shell code I need to be debug, so I had the code dump its environment into a file env > env.txt and with my testing script I want to source it, test.sh: . ./env.txt echo $EXAMPLE echo $EXAMPLE2 the contents of env.txt are: EXAMPLE=sh /hello/command.sh EXAMPLE2=/just/some/path but, env does not put quotes around its values, which tends to cause a issue for $EXAMPLE, I get this error test.sh: /hello/command.sh: not found so clearly it is trying to run it instead of setting the variables. what do you find is the quickest workaround for this problem? while read line; do declare "$line"
