I have a program that loads some tab-separated lines into a MySQL table. One of the values has tabs in it, which is causing some problems. The data is created column by column, so I need to find a way to strip the tab character out of an individual field with gsub. I do not, however, want to get rid of anything else, like spaces.

Ruby has lstrip and rstrip methods which can be used to remove leading and trailing whitespaces respectively from a string. Ruby also has strip method which is a combination of lstrip and rstrip and can be used to remove both, leading and trailing whitespaces, from a string.
gsub(/[[:space:]]/, '') - removes all whitespace, including unicode ones.
delete or . tr String method to delete the newlines.
Accessing Characters Within a String To print or work with some of the characters in a string, use the slice method to get the part you'd like. Like arrays, where each element corresponds to an index number, each of a string's characters also correspond to an index number, starting with the index number 0.
It's really easy \t is the tab character.
result = string.gsub /\t/, ''
or, in-place
string.gsub! /\t/, ''
