由 試著忘記壹切 提交于 2019-12-13 17:11:46
问题 I've a bash script that need to use some variables included in a separate file. Normally, for including the entire file I would use source otherfile.sh in the main script. In this case I need to use just a portion of this file. I can't use (include) the rest of the variables included in the rest of the file. To filter the content of the config file (let's say just as example from the tag "# start" to "# end") I use awk, but I can't redirect the output to the soruce command. Below my code: awk

What does if (@array) mean in perl?

由 Deadly 提交于 2019-12-13 14:36:29
问题 What does this mean in Perl? if (@array) if (!@array) Does this mean if we ask Perl to check if array exists or not? Thanks 回答1: An array in scalar context returns the number of elements. So the if(@array) checks if the array has any elements or not. It's similar to if(scalar(@array)!=0) . 回答2: In Perl, an array in scalar context evaluates to the number of elements in the array. So my @array = ('a', 'b'); my $n = @array; sets $n to 2. Also, if applies a scalar context to its parameter. So my

Delete first line of text file

由 怎甘沉沦 提交于 2019-12-13 11:33:18
问题 I need a cmd script that deletes the first line in my text file. The scenario is the following: I take a txt file from FTP everyday, the problem is that it comes with blank line at the top then the headers of the file. Since I'm importing that file automatically into an access table, that blank line is causing me problems. So, I need a script that deletes the blank line and saves the file. 回答1: Windows/command prompt: more +1 filename.ext > otherfilename.ext That seems to work fine, however

Cygwin save package selections for later reinstall

由 跟風遠走 提交于 2019-12-13 11:32:32
问题 I was wondering if there is a way to save the current package selections for cygwin for a later reinstall or porting on a different system. It would be really great to: run a command to export a list of installed packages on an existing system pass the list to the installer on another system in a way such as setup-x86_64.exe --list list.txt I don't think the setup has such a switch, so even any type of script or batch working in this direction would be just fine. Since the number of needed
