If you want to do it in pure bash, use the following script:<\/p>\n

#!\/bin\/bash\nwhile read line; do\n  line=( ${line\/\/[:]\/ } )\n  for i in \"${!line[@]}\"; do\n    [ ! -z \"${line[$i]##*[!0-9]*}\" ] && printf \"integer\" || printf \"string\"\n    [ \"$i\" -ne $(( ${#line[@]} - 1)) ] && printf \":\" || echo\n  done\ndone < $1\n<\/code><\/pre>\n
Pass your file as first argument.<\/p>\n
This script iterates over all lines in file (while read line; do ... done < $1<\/code>, where $1<\/code> is the file path), then it replaces all colons in each line with spaces (${line\/\/[:]\/ }<\/code>). A variable with values separated with spaces can be treated as an array, and that’s why this substitution is in brackets.<\/p>\n
Now we can iterate over all values in a line. For each index in the line<\/code> array we:<\/p>\n
    \n
  1. Check if it contains digits only. It is done by removing all digits from current value in line (${line[$i]##*[!0-9]*}<\/code>, where line[$i]<\/code> is the current value) and then checking if it’s empty (! -z<\/code>). If it is, then we print integer<\/code>, or otherwise string<\/code>.<\/li>\n
  2. Check if this is not the last element in array. It is done by comparing current index ($i<\/code>) with the array length (${#line[@]}<\/code>) decreased by 1. If current index is not the last, we print :<\/code>. Otherwise, we print new line.<\/li>\n<\/ol>\n
    This is done for all lines in a given file. Given an input file with the following content:<\/p>\n
    col1:col2:col3:col4\n1:word:2:word2\nword3:3:word4:4\n<\/code><\/pre>\n
    We get the following result:<\/p>\n
    string:string:string:string\ninteger:string:integer:string\nstring:integer:string:integer\n<\/code><\/pre>\n<\/p><\/div>\n
