| 0 | 49 **What it does** |
| 50 | |
| 51 This tool runs the unix **awk** command on the selected data file. | |
| 52 | |
| 53 .. class:: infomark | |
| 54 | |
| 7 | 55 **TIP:** |
| 1 | 56 |
| 7 | 57 This tool uses the **extended regular** expression syntax (not the perl syntax). |
| 1 | 58 **\\d**, **\\w**, **\\s** etc. are **not** supported. |

63 - Awk by Example (http://www.ibm.com/developerworks/linux/library/l-awk1/index.html) |
| 0 | 64 - Long AWK tutorial (http://www.grymoire.com/Unix/Awk.html) |
| 65 | |

| 67 | |
| 68 **AWK programs** | |
| 69 | |
| 70 Most AWK programs consist of **patterns** (i.e. rules that match lines of text) and **actions** (i.e. commands to execute when a pattern matches a line). | |
| 71 | |
| 72 The basic form of AWK program is:: | |
| 73 | |
| 74 pattern { action 1; action 2; action 3; } | |
| 75 | |
| 76 | |
| 77 **Pattern Examples** | |
| 78 | |
| 79 - **$2 == "chr3"** will match lines whose second column is the string 'chr3' | |
| 80 - **$5-$4>23** will match lines that after subtracting the value of the fourth column from the value of the fifth column, gives value alrger than 23. | |
| 81 - **/AG..AG/** will match lines that contain the regular expression **AG..AG** (meaning the characeters AG followed by any two characeters followed by AG). (This is the way to specify regular expressions on the entire line, similar to GREP.) | |
| 82 - **$7 ~ /A{4}U/** will match lines whose seventh column contains 4 consecutive A's followed by a U. (This is the way to specify regular expressions on a specific field.) | |
| 6 | 83 - **10000 < $4 && $4 < 20000** will match lines whose fourth column value is larger than 10,000 but smaller than 20,000 |

84 - **BEGIN** will be executed once only, before the first input record is read. |
| 0 | 85 - If no pattern is specified, all lines match (meaning the **action** part will be executed on all lines). |

| 0 | 89 **Action Examples** |
| 90 | |
| 91 - **{ print }** or **{ print $0 }** will print the entire input line (the line that matched in **pattern**). **$0** is a special marker meaning 'the entire line'. | |
| 92 - **{ print $1, $4, $5 }** will print only the first, fourth and fifth fields of the input line. | |
| 93 - **{ print $4, $5-$4 }** will print the fourth column and the difference between the fifth and fourth column. (If the fourth column was start-position in the input file, and the fifth column was end-position - the output file will contain the start-position, and the length). | |

94 - **{ FS = "," }** can be used to change the field separator (delimeter) for parsing the input file. |
| 0 | 95 - If no action part is specified (not even the curly brackets) - the default action is to print the entire line. |
| 96 | |
| 97 | |
| 98 **AWK's Regular Expression Syntax** | |
| 99 | |
| 7 | 100 The select tool searches the data for lines containing or not containing a match to the given pattern. A Regular Expression is a pattern descibing a certain amount of text. |
| 0 | 101 |
| 102 - **( ) { } [ ] . * ? + \ ^ $** are all special characters. **\\** can be used to "escape" a special character, allowing that special character to be searched for. | |
| 103 - **^** matches the beginning of a string(but not an internal line). | |
| 104 - **(** .. **)** groups a particular pattern. | |
| 105 - **{** n or n, or n,m **}** specifies an expected number of repetitions of the preceding pattern. | |
| 106 | |
| 107 - **{n}** The preceding item is matched exactly n times. | |
| 7 | 108 - **{n,}** The preceding item ismatched n or more times. |
| 109 - **{n,m}** The preceding item is matched at least n times but not more than m times. | |
| 0 | 110 |
| 111 - **[** ... **]** creates a character class. Within the brackets, single characters can be placed. A dash (-) may be used to indicate a range such as **a-z**. | |
| 112 - **.** Matches any single character except a newline. | |
| 113 - ***** The preceding item will be matched zero or more times. | |
| 114 - **?** The preceding item is optional and matched at most once. | |
| 115 - **+** The preceding item will be matched one or more times. | |
| 116 - **^** has two meaning: | |
| 7 | 117 - matches the beginning of a line or string. |
| 0 | 118 - indicates negation in a character class. For example, [^...] matches every character except the ones inside brackets. |
| 119 - **$** matches the end of a line or string. | |
| 7 | 120 - **\|** Separates alternate possibilities. |
