col1      col2      col3      ..... coln-1   coln   [number   number    number    ..... number]  number

i want remove [ first , ] second last column using bash script

with sed 's/]//g' file, can remove ]. have error [ same statement.

your approach sed sound. need know [ , ] special characters in (all flavors of) regular expressions, therefore need escaping backslashes. , name choice of 2 characters, […] used, so:

sed 's/[\[\]]//g' test.csv

this, however, can done quicker using tr can remove given characters:

tr -d '[]' < test.csv > test2.csv
