為imagemagick運行bash腳本時，mkdir卡住了

Question

運行imagemagick bash腳本時，我試圖寫入驅動器上的特定目錄/文件夾。

到目前為止，我可以為腳本添加參數，以便使用參數值在要輸出imagemagick文件的位置創建一個新目錄（文件夾）。 我設法在bash腳本中使用傳遞給mkdir命令的參數創建一個新目錄。 但是，腳本會在執行mkdir命令的最后卡住，並且永遠不會繼續執行。

這將導致創建目錄，但是我再也沒有機會在新目錄中寫入文件。 以后我可以找到創建的目錄，但其中沒有任何內容。 我嘗試了兩種不同的方式來創建目錄，但都被卡住了。

當我在終端中調用腳本時，它會執行所有步驟，直到到達mkdir命令，然后終端凍結，就像它正在等待發生的事情一樣，因此它可以繼續前進-多次按ENTER也無濟於事； ）-而且我沒有感覺它陷入了循環。

我正在運行一個mkdir命令，作為對我嘗試輸出到輸出目錄時未在寫入之前創建輸出目錄時收到的err msgs的響應。

我在OSX El Capitan上運行bash，以下是與我的問題相關的腳本的選定片段。

#!/bin/bash

args=("$@")

employer=${args[2]}
position=${args[3]}

output_dir="${employer} - ${position}"

# mkdir -pv -m u=rwx "$output_dir"
[ -d "$output_dir" ] && echo "Output Directory Exists" || mkdir -pv -m u=rwx "$output_dir"

# imagemagick script where a new image file gets written to my new output_dir
# the final string is the output path of my new imagemagick image output 
convert - $logo_path -gravity center -geometry 350x350+280+70 -composite -set 
filename:dimensions '%wx%h' 
"${output_dir}/LN-${employer}-${position}-%[filename:dimensions].png"

編輯：

在第一條評論和回復之后，我有義務向大家提供完整的代碼，也許您可​​以找到一些東西。 =）另外，正如我在下面的評論中提到的那樣，按照ShellCheck的指示（根據評論中的@Cyrus的建議）清除shell腳本問題使imagemagick命令混亂，並且輸出失敗。 因此，我已恢復到舊代碼，以便從此處逐步糾正代碼，同時保持所需的輸出（生成的舊代碼（根據ShellCheck，它是越野車））。 請參見下面的代碼。

我在使用ShellCheck進行調試時所做的更改無法解決mkdir掛起的主要問題。 在$folder_path創建新目錄時，我仍然失敗，因為它永遠不會繼續使用最后一個convert命令實際輸出圖像。

在用ShellCheck調試之后，我遇到的其他問題是，當我嘗試在convert命令中使用$custpath它根本無法工作，這就是為什么我現在在convert命令中使用$custpath的整個值的$custpath 。 我已嘗試按照ShellCheck的建議使用$"{custpath[@]}"和$"{custpath[*]}" ，但它們均未成功創建輸出，因為-猜怎么-使用$custpath掛起腳本。

我正在嘗試將輸出圖像放入$custpath$folder_path$output_dir文件夾中。

這是整個腳本：

Answer 1

您的命令：

convert - ...

嘗試從其標准輸入讀取圖像。 因此，除非您在標准輸入上提供圖像，否則它將永遠掛起：

cat someImage.jpg | yourScript arg1 arg2

或之后命名圖片：

convert someImage.jpg ...

也許$logo_path已經是圖像的名稱，在這種情況下，您將需要：

convert "$logo_path" ...

順便說一句，@ Jdamian的建議是一個好建議，具體來說，這意味着將您的第一行更改為：

#!/bin/bash -x

Answer 2

我通過將其掛到~/.bash_profile並使用自定義的mkdir命令來解決了掛起的mkdir的問題，如下所示：

mk () {
  case "$1" in /*) :;; *) set -- "./$1";; esac
  mkdir -p "$1" #&& cd "$1"
}

# call the socmed function like so
# socmed day month "employer" "position" "path to logo"
function socmed {
  args=("$@")

  echo
  echo date1 = "${args[0]}"
  echo date2 = "${args[1]}"
  echo employer = "${args[2]}"
  echo position = "${args[3]}"
  echo logo_path = "${args[4]}"


  employer=${args[2]}
  position=${args[3]}
  logo_path=${args[4]}
  folder_path=${logo_path/%\/*//}
  custpath="$HOME/Dropbox/+ B-folder/A Folder/Gfx/Logos/"
  output_dir="${employer} - ${position}"
  mk "$custpath"/"$folder_path"/"$output_dir"

  echo custpath = "$custpath"
  echo folder_path = "$folder_path"
  echo output_dir = "$output_dir"
  echo

  ./full-tw.sh "${args[0]}" "${args[1]}" "${args[2]}" "${args[3]}" "${args[4]}"
  ./full-insta.sh "${args[0]}" "${args[1]}" "${args[2]}" "${args[3]}" "${args[4]}"
  ./full-ln.sh "${args[0]}" "${args[1]}" "${args[2]}" "${args[3]}" "${args[4]}"
  ./full-fb.sh "${args[0]}" "${args[1]}" "${args[2]}" "${args[3]}" "${args[4]}"
}

不必將問題向上推一級，因為我的意圖是無論如何都要使用bash配置文件，以便同時創建許多圖像。 =）
