通过do while逐行编辑

Question

如何在while循环中编辑文件的行，Code除了＆＃34之外的内容有效;如果＆＃34;声明，之前有人这样做过吗？ （今天第二个问题，谢谢）

#!/bin/bash
export ELMS_STORAGE="/loc1/f1.csv" 
export CUSTOMER_LIST="/loc2/f2.csv"
while read -r ELMS_SIZE ELMS_NAME ELMS_ENV do while IFS=, read -r
CUSTOMER_ENV CUSTOMER_URI CUSTOMER_NAME CUSTOMER_SCHEMA_OWNER
CUSTOMER_DB_INSTANCE OTHER do


if [ "${ELMS_NAME}" = "${CUSTOMER_URI}" ]; then
#### add a new item to the f2.csv 
${ELMS_STORAGE}.${ELMS_ENV}="${ELMS_ENV} ${CUSTOMER_URI}"   ### doesn't work 
fi


done < <(tac $CUSTOMER_LIST) done < <(tac $ELMS_STORAGE)

exit

编辑前

f2.csv

monkey
dog
tiger

编辑后

f2.csv

monkey brown 
bird green 
cat yellow

Answer 1

尝试paste，这可能是你想要的

$ paste f1.csv f2.csv 
monkey  brown
dog green
tiger   yellow
