Dear All,
For example the content of data.txt file is:
1 1 23
2 1 42
3 2 52
4 2 62
5 1 77
6 1 88
7 2 99
8 1 100
Could I substitute 2 in second column with 1 using sed commad so that the data will be change as follow ?
1 1 23
2 1 42
3 1 52
4 1 62
5 1 77
6 1 88
7 1 99
8 1 100
is it also possible to change only one of them (e.g only second column third line) so that the data become:
1 1 23
2 1 42
3 2 52
4 1 62
5 1 77
6 1 88
7 2 99
8 1 100
thank you for you help in advance
best regards,
