[英]Handling wildcard expansion from a string array in a bash shell scripting
以下是我編寫的示例腳本
line="/path/IntegrationFilter.java:150: * <td>http://abcd.com/index.do</td>"
echo "$line" <-- "$line" prints the text correctly
result_array=( `echo "$line"| sed 's/:/\n/1' | sed 's/:/\n/1'`)
echo "${result_array[0]}"
echo "${result_array[1]}"
echo "${result_array[2]}" <-- prints the first filename in the directory due to wildcard character * .
從陣列中檢索時如何打印文本“* http://abcd.com/index.do”而不是文件名?
假設bash是正確的工具,有幾種方法:
禁用擴展:
line="/path/IntegrationFilter.java:150: * <td>http://abcd.com/index.do</td>"
set -f
OIFS=$IFS
IFS=$'\n'
result_array=( `echo "$line"| sed 's/:/\n/1' | sed 's/:/\n/1'`)
IFS=$OIFS
set +f
echo "${result_array[0]}"
echo "${result_array[1]}"
echo "${result_array[2]}"
(注意我們還必須設置IFS,否則內容的每個部分都以result_array [2],[3],[4]等結尾)
使用閱讀:
line="/path/IntegrationFilter.java:150: * <td>http://abcd.com/index.do</td>"
echo "$line"
IFS=: read file number match <<<"$line"
echo "$file"
echo "$number"
echo "$match"
使用bash參數擴展/替換:
line="/path/IntegrationFilter.java:150: * <td>http://abcd.com/index.do</td>"
rest="$line"
file=${rest%%:*}
[ "$file" = "$line" ] && echo "Error"
rest=${line#$file:}
number=${rest%%:*}
[ "$number" = "$rest" ] && echo "Error"
rest=${rest#$number:}
match=$rest
echo "$file"
echo "$number"
echo "$match"
怎么樣:
$ line='/path/IntegrationFilter.java:150: * <td>http://abcd.com/index.do</td>'
$ echo "$line" | cut -d: -f3-
* <td>http://abcd.com/index.do</td>
