Exchange two folder names in bash

To fix this issue I'm not sure that you can do this atomically, but the time gap between three calls to mv in a small script or bash function will be small and likely sufficient for most people's needs. eg.
function altdir { mv $1 $1-alttmp; mv $1-alt $1; mv $1-alttmp $1-alt; }

How to exchange multiple columns

it fixes the issue Using Microsoft Excel 2010, I have a spreadsheet containing data from 5 different datafiles (each having 14 columns, so 70 columns together). What I need to do, is to sort these columns in this fashion: 1.,15.,29.,43.,57.,2.,16.,...etc. , Start by using the following formula in your final spreadsheet:
=INDEX({"Sheet1";"Sheet2";"Sheet3";"Sheet4";"Sheet5"},MOD(COLUMN()-1,5)+1)
=QUOTIENT(COLUMN()-1, 5)+1
=ADDRESS(ROW(),QUOTIENT(COLUMN()-1, 5)+1,1,1,INDEX({"Sheet1";"Sheet2";"Sheet3";"Sheet4";"Sheet5"},MOD(COLUMN()-1,5)+1))
Sheet1!$A$1 Sheet2!$A$1 Sheet3!$A$1 Sheet4!$A$1 Sheet5!$A$1 Sheet1!$B$1 Sheet2!$B$1 Sheet3!$B$1 Sheet4!$B$1 Sheet5!$B$1
Sheet1!$A$2 Sheet2!$A$2 Sheet3!$A$2 Sheet4!$A$2 Sheet5!$A$2 Sheet1!$B$2 Sheet2!$B$2 Sheet3!$B$2 Sheet4!$B$2 Sheet5!$B$2
Sheet1!$A$3 Sheet2!$A$3 Sheet3!$A$3 Sheet4!$A$3 Sheet5!$A$3 Sheet1!$B$3 Sheet2!$B$3 Sheet3!$B$3 Sheet4!$B$3 Sheet5!$B$3
=INDIRECT(ADDRESS(ROW(),QUOTIENT(COLUMN()-1, 5)+1,1,1,INDEX({"Sheet1";"Sheet2";"Sheet3";"Sheet4";"Sheet5"},MOD(COLUMN()-1,5)+1)))

Exchange the position of two string through bash

Does that help If you happen to only have strings with 1 or 2 characters, you can reverse them. And oh, there is the rev command in UNIX:
zone=$(echo "$zone" | rev)
zone=$(rev <<< "$zone")
$ zone="E"
$ rev <<< "$zone"
E

$ zone="A1"
$ rev <<< "$zone"
1A
 rev — reverse lines of a file or files

I wish did fix the issue. If you can rely on the ordering always being 56, 57, 58, 59, then you can do this with sed:
sed -E 's/(56:)([0-9]+)(.*57:)([0-9]+)(.*58:)([0-9]+)(.*59:)([0-9]+)/\1\6\3\8\5\2\7\4/' file

will be helpful for those in need I have data , Another option:
dtmode <- function(x) x[which.max(rowid(x))]
test[, .(A=unique(A), B=dtmode(B), C=dtmode(C))] 
test = data.table(
    A = c(1,1,3,4,5,6), 
    B = c("a", "be", "a", "c", "d", "c"), 
    C = rep(1, 6)
)
