Bash Script to Rename Files then Sync Files (router configs) from TFTP to Git

问题

I created a script so when a cisco router config is saved its sent to a TFTP server, i would like to rename the config (as cisco appends the time) from
PHC-16JUB-SW01.txt-Jul-20-2023-04-13-57.744-UTC-30
to
PHC-16JUB-SW01.txt
I am doing this so when i commit to GIT its not a "unique" file.

Once the file has been renamed, its then sent to GIT for auditing/backup

im not proficient in coding, this is my best try from all the SO and github scripts out there.

  1. #!/bin/bash
  3. file_closed() {
  4.   FILENAME=$(echo $FILE | grep -o '^.*\.txt')
  5.   OUTPUT=$(eval $FILENAME)
  6.   mv "$DIRECTORY/$FILE" "$DIRECTORY/$OUTPUT"
  7. }
  9. git_commit() {
  10.   DATE_FMT=$(date +"%Y-%m-%d %H:%M:%S")
  11.   cd /var/lib/tftpboot/$DIRECTORY
  12.   git add .
  13.   git commit -m "Config updated ($DATE_FMT)"
  14.   git push
  15. }
  17. inotifywait -q -m -r -e close_write $1 | while read DIRECTORY EVENT FILE; do
  18.   case $EVENT in
  19.     CLOSE*)
  20.       file_closed "$DIRECTORY" "$FILE"
  21.       git_commit
  22.       ;;
  23.   esac
  24. done

Executing the script will commit the changes to GIT but also get stuck in a loop trying to "mv" other files.

感谢Kurtis Rader的建议。我运行了以下代码，它完美地工作。

  1. #!/bin/bash
  3. file_closed() {
  4.     local FILE="$1"
  5.     local FILENAME="${FILE%%.txt-*}.txt"
  6.     mv "$DIRECTORY/$FILE" "$DIRECTORY/$FILENAME"
  7. }
  9. git_commit() {
  10.     local DIRECTORY="$1"
  11.     local DATE_FMT=$(date +"%Y-%m-%d %H:%M:%S")
  12.     cd "/var/lib/tftpboot/$DIRECTORY"
  13.     git add .
  14.     git commit -m "Config updated ($DATE_FMT)"
  15.     git push
  16. }
  18. while read -r DIRECTORY EVENT FILE; do
  19.     case $EVENT in
  20.         CLOSE*)
  21.             file_closed "$FILE"
  22.             git_commit "$DIRECTORY"
  23.             ;;
  24.     esac
  25. done < <(inotifywait -q -m -e close_write --format '%w %e %f' "$1")

在这个修正后的版本中，我们正确传递了DIRECTORY和FILE变量给函数。我们使用参数扩展来提取不带时间戳的基本文件名，而不是在file_closed函数中。git_commit函数现在接受DIRECTORY作为参数。inotifywait命令使用--format选项来获取有关事件的必要信息。

thanks to Kurtis Rader suggestion.. i ran the code through ChatGPT and got the below code, which works flawlessly.

  1. #!/bin/bash
  3. file_closed() {
  4.     local FILE=&quot;$1&quot;
  5.     local FILENAME=&quot;${FILE%%.txt-*}.txt&quot;
  6.     mv &quot;$DIRECTORY/$FILE&quot; &quot;$DIRECTORY/$FILENAME&quot;
  7. }
  9. git_commit() {
  10.     local DIRECTORY=&quot;$1&quot;
  11.     local DATE_FMT=$(date +&quot;%Y-%m-%d %H:%M:%S&quot;)
  12.     cd &quot;/var/lib/tftpboot/$DIRECTORY&quot;
  13.     git add .
  14.     git commit -m &quot;Config updated ($DATE_FMT)&quot;
  15.     git push
  16. }
  18. while read -r DIRECTORY EVENT FILE; do
  19.     case $EVENT in
  20.         CLOSE*)
  21.             file_closed &quot;$FILE&quot;
  22.             git_commit &quot;$DIRECTORY&quot;
  23.             ;;
  24.     esac
  25. done &lt; &lt;(inotifywait -q -m -e close_write --format &#39;%w %e %f&#39; &quot;$1&quot;)

In this corrected version, we pass the DIRECTORY and FILE variables correctly to the functions. We use parameter expansion to extract the base filename without the timestamp in the file_closed function. The git_commit function now accepts the DIRECTORY as an argument. The inotifywait command is used with the --format option to get the necessary information about the event.
