crontab 中的错误，而不是控制台中的错误

Question

我有一个罕见的问题。

当我通过控制台执行文件时，它运行良好，但是当我通过 crontab 执行它（同一文件）时，我在代码的以下部分收到错误

join -j 1 -t ',' <(sort $dir/Xem3.csv) <(sort $dir/coordenades.csv)|awk -F "," '{print  $15","$16","$17"," $3"," $4","$18"," $5"," $6","$7","$8"," $9","$10","$11","$12","$13}' > $dir/Xem4.csv

crontab 日志中的错误是

/home/enric/proves/web.sh: line 95: syntax error near unexpected token `('
/home/enric/proves/web.sh: line 95: `join -j 1 -t ',' <(sort $dir/Xem3.csv) <(sort $dir/coordenades.csv)|awk -F "," '{print  $15","$16","$17"," $3"," $4","$18"," $5"," $6","$7","$8"," $9","$10","$11","$12","$13}' > $dir/Xem4.csv'

知道吗？

我的脚本是

#/bin/bash
dir=/home/enric/proves
join -j 1 -t ',' <(sort $dir/Xem3.csv) <(sort $dir/coordenades.csv)|awk -F "," '{print  $15","$16","$17"," $3"," $4","$18"," $5"," $6","$7","$8"," $9","$10","$11","$12","$13}' > $dir/Xem4.csv
tr -d 'r' < $dir/Xem4.csv > $dir/out.csv

你的第一行不是 shebang 行。你想要#!/usr/bin/env bash.如果没有感叹号，这一行只是另一个注释，脚本将在 cron 使用的 shell 中执行（通常/bin/sh）。 <(my_command)是一种害羞，因此语法错误。
