Thanks in advance for any help you can lend on this. The document I am working on has other patterns that differ from the four above, but if I can get the above four, that will be about 80% off the project, and will minimize a lot of hand editing to get the font treatments correct. Can someone assist me in getting a GREP statement that will identify any of these potential combinations. The operator associates the string with the regex match and produces a true value if the regex matched, or false if the regex did not match. And I'm not even sure mixing Nested Styles and GREP is a wise way to go. Either it would ignore the "$" sign, or the first two digits before the decimal place. The term string or character string is used by programmers to indicate a sequence of characters. I am writing a regular expression checker for QLineEdit and I am using QRegExp. The name stands for Global Regular Expression Print. t is supported as a regular expression metacharacter in awk, perl, and in a few implementations of sed. Grep is a powerful utility available by default on UNIX-based systems. Give a regular expression for identifying blank lines. However, most versions of sed do not recognize the t abbreviation, so when typing these scripts from the command line, you should press the TAB key instead. The Textbook, Second Edition Syed Mansoor Sarwar, Robert M Koretsky. I could never get the grep statement to completely work. I will indicate strings using regular double quotes. the expression t to indicate a tab character (0x09) in the scripts. I was able get partially there by doing the first two "% OFF" scenarios using nested styles, then trying to do the "$00.00" and "00.00" with a GREP statement. The name grep stands for global regular expression print. I want the GREP statement to identify the text that matches any or all of those patterns, so that I can apply the text styles. The grep command is one of the most useful commands in a Linux terminal environment. sed with a backreferece to reinsert the digits before the percent sign in the general substitution form is probably a bit more doable than grep.For example you can use: sed -E s/)+)s+(0-9+). One of the above four patterns will always appear at the beginning of the paragraph. Here are the patterns I am trying to identify in a single GREP statement:: I was able to get half of what I wanted using Nested Styles, but that solution doesn't seem to fit most of the cases in the files with which I am working. Alternatively the characters (except ) could be escaped by enclosing them between square. In all the cases special characters are escaped by backslash. The awk/ sed/ perl ones don't reflect whether any line matched the patterns in their exit status.I am attempting to format text by identifying it with GREP patterns, then applying styles via InDesign's paragraph and character styles. There are multiple types of regular expressions and the set of special characters depend on the particular type. Please beware that all those will have different regular expression syntaxes. Or perl: perl -ne 'print if /pattern1/ & /pattern2/' Or with sed: sed -e '/pattern1/!d' -e '/pattern2/!d' The best portable way is probably with awk as already mentioned: awk '/pattern1/ & /pattern2/' If the patterns don't overlap, you may also be able to do: grep -e 'pattern1.*pattern2' -e 'pattern2.*pattern1' *s as & matches strings that match both and exactly, a&b would never match as there's no such string that can be both a and b at the same time). With ast grep: grep -X '.*pattern1.*&.*pattern2.*' With GNU grep, when built with PCRE support, you can do: grep -P '^(?=.*pattern1)(?=.*pattern2)' re.search () checks for a match anywhere in the string (this is what Perl does by default) re.fullmatch () checks for entire string to be a match. But you don’t always have to figure out all the grep codes yourself Use the table below to find a grep expression that is close to what you’re looking for. Python offers different primitive operations based on regular expressions: re.match () checks for a match only at the beginning of the string. It shows up in several places in InDesign, notably the Find/Change dialog box and the GREP Styles feature. To find the lines that match each and everyone of a list of patterns, agrep (the original one, now shipped with glimpse, not the unrelated one in the TRE regexp library) can do it with this syntax: agrep 'pattern1 pattern2' 157 GREP is an incredibly powerful technology for finding and replacing text.
