问题 I have to parse a file in the following format: line1_param1:line1_param2:line1_param3: line1_param2:line2_param2:line2_param3: line1_param3:line3_param2:line3_param3: And process it line by line, extracting all parameters from current line. Currently I've managed it in such a way: IFS=":" grep "nice" some_file | sort > tmp_file while read param1 param2 param3 do ..code here.. done < tmp_file unset IFS How can I avoid a creation of a temporary file? Unfortunately this doesn't work correctly:

Using IFS with echo [duplicate]

问题 This question already has answers here : How can I convert an array to a comma separated list in Bash? (5 answers) Why can't I set IFS for one call of printf (2 answers) Closed 5 months ago . Why does this: arr=(1 2 4 8 16) IFS=, echo "${arr[*]}" print out 1,2,4,8,16 (which is what I want) but this doesn't: arr=(1 2 4 8 16) IFS=, echo "${arr[*]}" ? I'd like to have a temporary IFS without having to set it then reset/unset it. 来源： https://stackoverflow.com/questions/57627024/using-ifs-with

E_BADARGS=65 # 传递给脚本的参数个数不对. echo "Args number is : $#" echo $0 if [ $# -ne "$ARGS" ] # 测试脚本的参数个数。 then echo "Usage: $(basename $0) first-parameter second-parameter third-parameter" exit $E_BADARGS fi # 开始干正事儿 在上面的代码中我们使用了 $(basename $0) 的写法，这是因为 $0 会包含脚本文件的路径，为了让输出看起来清爽一些，我用 $(basename $0)
