with a previous bash script I created a list of files:
data_1_box
data_2_box
...
data_10_box
...
data_99_box
the thing is that now I need to concatenate them, so I tried
ls -l data_*
but I get
.....
data_89_box
data_8_box
data_90_box
...
data_99_box
data_9_box
but I need to get in the sucession 1, 2, 3, 4, .. 9, ..., 89, 90, 91, ..., 99
Can it be done in bash?
ls data_* | sort -n -t _ -k 2
-n: sorts numerically
-t: field separator '_'
-k: sort on second field, in your case the numbers after the first '_'
How about using the -v
flag to ls
? The purpose of the flag is to sort files according to version number, but it works just as well here and eliminates the need to pipe the result to sort
:
ls -lv data_*
