Problem:<\/p>\n

– You have several CSV file that have a title that needs to change.<\/p>\n

In my example I had a column name that was need to change from “Time(edt)” to just “Time”<\/p>\n

To run a test:<\/p>\n

note:\u00a0 no special backslash needed for “(” or “)”<\/p>\n

You can glob the files and it will do all of them.<\/p>\n

sed 's\/Time(edt)\/Time\/g' KDCA_3_day_Y*.csv\r\n<\/pre>\n
Add the -i to do the deed in place<\/p>\n
 <\/p>\n
sed -i 's\/Time(edt)\/Time\/g' KDCA_3_day_Y*.csv<\/pre>\n
For BSD – I got an error<\/p>\n
 <\/p>\n
[jon2allen@freebsd12_3 ~\/github\/weather_obs]$ sed -i 's\/Time(edt)\/Time\/g' KDCA_3_day_Y*.csv\r\nsed: 1: \"KDCA_3_day_Y2022_M09_D2 ...\": invalid command code K\r\n<\/pre>\n
The man page suggest that the -i flag can have a backup extension, and a zero byte would ignore it which doesn’t seem to be the case.<\/p>\n
 <\/p>\n
sed -ibak 's\/Time(edt)\/Time\/g' KDCA_3_day_Y*.csv\r\n<\/pre>\n
It simply tacks on the extension to the end.<\/p>\n
