Top Forums Shell Programming and Scripting Parsing a subset of data from a large matrix Post 302980578 by Don Cragun on Tuesday 30th of August 2016 11:54:30 AM

What operating system are you using?

What shell are you using?

What have you tried to solve this problem?

Note that *-ab1-* is a valid filename matching pattern, but it is not a valid regular expression. (A BRE or ERE to match a string contain the string -ab1- anywhere in the string would be .*-ab1-.* or just -ab1-.)

Since you have not shown us tab-delimited data, it is hard to guess at exactly what you mean. The data you have shown us seems to have room for multiple tabs between fields on the data lines (which should not happen in a tab-delimited file). Other than the heading line (where I assume there is exactly one tab at the start of the line and a single tab between field headings), will there ever be any field that is empty? Will there ever be any <space> characters in your data?

NAME
XmTabList -- Data type for a tab list SYNOPSIS
#include <Xm/Xm.h> XmTabList DESCRIPTION
XmTabList is the data type for a tab list. A tab list consists of tab stop list entries (XmTabs). Whenever a tab component is encountered while an XmString is being rendered, the origin of the next X draw depends on the next XmTab. If a tab stop would cause text to overlap, the x position for the segment is reset to follow immediately after the end of the previous segment. Tab lists are specified in resource files with the following syntax: resource_spec: tab WHITESPACE [, WHITESPACE tab ]* The resource value string consists of one or more tabs separated by commas. Each tab identifies the value of the tab, the unit type, and whether the offset is relative or absolute. For example: tab := float [ WHITESPACE units ] float := [ sign ] [[ DIGIT]*. ]DIGIT+ sign := + where the presence or absence of sign indicates, respectively, a relative offset or an absolute offset. Note that negative tab values are not allowed. units indicates the unitType to use as described in the XmConvertUnits reference page. For example, the following specifies a tab list consisting of a one inch absolute tab followed by a one inch relative tab: *tabList: 1in, +1in For resources of type, dimension, or position, you can specify units as described in the XmNunitType resource of the XmGadget, XmManager, or XmPrimitive reference page.
