Hello,
Can you explain why in the first 2 commands the awk does not print anything? Is it looking of a specific format ?
Thanks.
$ echo 12a3 | awk '($1>=2) {print $1}' # prints nothing
$ echo 123a | awk '($1>=2) {print $1}' # prints nothing
$ echo a123 | awk '($1>=2) {print $1}'

I do not know how to do this unless I use a bunch of if statements. I need a script to replace numbers in each record in a file. I am really getting tangled in this web.
If a fieldA (19 positions) is greater than 14 digits, I have to change the data (resulting fieldA is fixed 19 postions).

Hi Everyone,
# cat 1
1;2;3;4;5;6
1;2;3;4;5;
# awk -F ";" '$5 == "5"' 1
1;2;3;4;5;6
1;2;3;4;5;
but the output is should be just "1;2;3;4;5;6" means 1st condition: $5 is 5; 2nd condition: $6 is not empty, please advice. Thanks (2 Replies)
Hi there,
I wanna define a variable 'tempbase'. Therefore I read a text file "base.out". "base.out" contains a list with four columns. 'tempbase' is the 4th entry in the line, where the first entry is equal to the predefined variable $orb1 and the second entry is equal to $orb2. I wrote the code... (2 Replies)
Hi there, here is my command

The problem is if conditional 1 is met (i.e $4 > 120), i don't see "My error message", the... (5 Replies)

hello gurus,
I want to use an associative array from a file to populate a field of another file, by matching several columns in order of priority. If the first column matches, then i dont want to match $2. Similarly I only want to match $3 when $1 and $2 are not in associative array.
For the... (6 Replies)

xmlif - conditional processing instructions for XML
SYNOPSIS
xmlif [attrib=value...]
DESCRIPTION
xmlif filters XML according to conditionalizing markup. This can be useful for formatting one of several versions of an XML document
depending on conditions passed to the command.
Attribute/value pairs from the command line are matched against the attributes associated with certain processing instructions in the
document. The instructions are <?xmlif if?> and its inverse <?xmlif if not?>, <?xmlif elif?> and its inverse <?xmlif elif not?>, <?xmlif
else?>, and <?xmlif fi?>.
Argument/value pairs given on the command line are checked against the value of corresponding attributes in the conditional processing
instructions. An `attribute match' happens if an attribute occurs in both the command-line arguments and the tag, and the values match. An
`attribute mismatch' happens if an attribute occurs in both the command-line arguments and the tag, but the values do not match.
Spans between <?xmlif if?> or <?xmlif elif?> and the next conditional processing instruction at the same nesting level are passed through
unaltered if there is at least one attribute match and no attribute mismatch; spans between <?xmlif if not?> and <?xmlif elif not?> and the
next conditional processing instruction are passed otherwise. Spans between <?xmlif else?> and the next conditional-processing tag are
passed through only if no previous span at the same level has been passed through. <?xmlif if?> and <?xmlif fi?> (and their `not'
variants) change the current nesting level; <?xmlif else?> and <?xmlif elif?> do not.
All these processing instructions will be removed from the output produced. Aside from the conditionalization, all other input is passed
through untouched; in particular, entity references are not resolved.
Value matching is by string equality, except that "|" in an attribute value is interpreted as an alternation character. Thus, saying
foo='red|blue' on the command line enables conditions red and blue. Saying color='black|white' in a tag matches command-line conditions
color='black' and color='white'.
Here is an example:
Always issue this text.
<?xmlif if condition='html'?>
Issue this text if 'condition=html' is given on the command line.
<?xmlif elif condition='pdf|ps'?>
Issue this text if 'condition=pdf' or 'condition=ps'
is given on the command line.
<?xmlif else?>
Otherwise issue this text.
<?xmlif fi?>
Always issue this text.
