unix - Error when starting script : No such file or directory while executing a shell script -

-

I have only encountered the problem as described on

: Question by user: "I am getting: There is no such file or directory when executing the shell script, but I have this file in this file and it also has executable rights."

Answer: "Did you Started the name of your script / directory / script or ./scriptname? "

Worked for the time being, once I started the script using "./scriptname" I started this script on multiple servers and on some machines I could use "script name" and others could have "./scriptname" "Why was it necessary to" use on some machines "but not" on others "? File permission is the same on all machines.

If the current directory (. ) PATH You can run a script in both ways: 

  will see script.sh in every directory listed in script.sh # Shell # in $ PATH ./script.sh # Shell will invite # script.sh located in the current directory.   
 If the current directory is not in the  PATH , then you have to run it like this:  
  ./ script   
 That's because Shell will not know where this script is from - its original folder is not in the  PATH . Open it with  ./  and tell where it got it from.  
 
 
 
 
  
 
  
 
 
 
  The colon is delimited, the above version means "The new path will be similar to the old path with the addition of an existing directory (. )".  
  Edit:  Note: @Carryl Comment - Put .  in  PATH  is not a good idea (reason for security).

After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
