bashシェルスクリプト言語が変更されましたか？ [閉鎖]

数年前、私はrsyncというマルチパートスクリプトを書いていましたが、いつも働きました。 1年間使用せずに多数のdebian apt-getアップデートを行った後、スクリプトの動作が停止しました。

Main2Network1.sh は Main2Network2 を呼び出し、パート 3 と 4 を含みますが、Main2Network1.sh スクリプトの 27 行目には以下が含まれます。

 Main2Network1.sh: [[ not found 

27号線は

if [[ -z $VAR ]];

スクリプトを作成するときは、if thenに[[]]スクリプトが必要で、Enterキーを押すと機能します。https://stackoverflow.com/a/20201920/9383998

おそらく、誰かが私のコードの27行の周りに最近使用されなくなった構文が表示されているかどうかを知らせることができます（スクリプトを実行したときにエラーが発生する場所はここにあります）。みんなありがとう

Main2Network1.sh

 #!/bin/bash
#renames files changed files on NETWORK to _day_mnth_yr_NETWORK1 then puts maincomp version of file on network.
#THIS SHOULD BE PUT TO AUTOMATICALLY RUN AFTER TRAVEL2NETWORK SYNC
#info=NAME1 lists just changed Files/Dirs, -b must preceed --suffix,
# this will change existing dup file on travel to date_TRAVEL replacing base file with network version
#SOURCE File Dups replace network and network copy renamed to _NETWORK1
