Refering to something that Benno wrote I was hoping that it would start
nano and after save it would convert spaces 2 tab but now I realize that
it doesnt work like that. However it doesent seem to work:


    $ spc2tab.sh <anyfilename
    grep: ^[[:blank:]]*set[[:blank:]]+tabsize[[:blank:]]+[1-9][0-9]*: No
    such file or directory
    /usr/local/bin/spc2tab.sh: line 10: :a;s@^\(*\)        @\1@;ta:
    command not found
    $ cat anyfilename
    this                               have               many       
    spaces
    $ cat /usr/local/bin/spc2tab.sh
    #!/usr/bin/env bash
    # spc2tab - Convert leading spaces into tabs
    # Required: sed
    # Usage: spc2tab <file
    nanoconf=~/.nanorc s='[[:blank:]]'
    tabsize=$(grep -eo "^$s*set$s+tabsize$s+[1-9][0-9]*" "$nanoconf"
    |tail -1 |grep -o '[0-9]*$')
    # Use given tabsize or 8 as (nano) default
    tabsize=${1:-8}
    spc=$(printf '%*s' $tabsize)
    tab=$'\t'sed ":a;s@^\($tab*\)$spc@\1$tab@;ta" </dev/stdin
    $
    
    I have a .nanorc that just says set tabsize 8 and nothing more.
