使用Shell脚本从文件名重命名特定的字符串

Question

I have to rename the filename with some specific keywords changed.

**Input FileName :**
master_1800_20181217120005.csv
master_2300_20181217120005.csv
master_2300_addcarrier_20181217120005.csv
master_2300_XNB_20181217120005.csv
master_2300_XNB_addcarrier_20181217120005.csv
master_850_20181217120005.csv
master_850_addcarrier_20181217120005.csv
master_IBS_20181217120005.csv
master_Smallcell_20181217000500.csv

Output FileName: master_1800_ $(date -d '1 day ago' +%Y%m%d) 120005.csv master_2300_ $(date -d '1 day ago' +%Y%m%d) 120005.csv master_2300_addcarrier_ $(date -d '1 day ago' +%Y%m%d) 120005.csv master_2300_XNB_ $(date -d '1 day ago' +%Y%m%d) 120005.csv master_2300_XNB_addcarrier_ $(date -d '1 day ago' +%Y%m%d) 120005.csv master_850_ $(date -d '1 day ago' +%Y%m%d) 120005.csv master_850_addcarrier_ $(date -d '1 day ago' +%Y%m%d) 120005.csv master_IBS_ $(date -d '1 day ago' +%Y%m%d) 120005.csv master_Smallcell_ $(date -d '1 day ago' +%Y%m%d) 000500.csv

I tried using $(rename 's/20181217/20181218/' ) but no luck.

Answer 1

rename 20181217 20181218 master_*.csv可能会解决问题

Answer 2

This work: rename 's/20181217/20181218/' YOUR_FILE_NAME

Or you can use sed, before you redirect you output to the target file.
