\| is a GNU extension. There is no alternation operator in standard basic regular expression grammar. Outside of GNU (and Busybox, probably, since they explicitly model their implementation on GNU tools), I don't believe that will work anywhere.

Hello
I wrote simple one liner that take RunTime *.exe and link them to the output of the compilation output:

Hi,
I am trying to debug an old script and have found the problem lies within this function:
isIdoc() { # validate the file type
fileType=`file $1 | awk '{print $NF}'`
&& echo 0 || echo 1
}
My question is, how can I determine what is in the variable $fileType ? The program is... (1 Reply)
I would like to print result of multiple search pattern invoked from an one liner. The code looks like this but won't work
gawk -F '{{if ($0 ~ /pattern1/) pat1=$1 && if ($0 ~ /pattern2/) pat2=$2} ; print pat1, pat2}'
Can anybody help getting the right code? (10 Replies)
Thanks for giving your time and effort to answer questions and helping newbies like me understand awk.
I have a huge file, millions of lines, so perl takes quite a bit of time, I'd like to convert these perl one liners to awk.
Basically I'd like all lines with ISA sandwiched between... (9 Replies)
Hi All,
I have around 900 Select Sql's which I would like to run in an awk script and print the output of those sql's in an txt file.
Can you anyone pls let me know how do I do it and execute the awk script? Thanks. (4 Replies)
Given:
1,2,whatever,a,940,sot
how can i print from one particular field to the end of line?
awk -F"," '{print $2 - endofline}'
the delimiter just happens to be a comma "," in this case. in other cases, it could be hypens:
1---2---whatever---a---940---sot (4 Replies)
I have the following awk one-liner I came up with last night to gather some data. and it works pretty well (apologies, I'm quite new with awk, and don't know how to format this pretty-printed). You can see the output with it.

PERLCC(1) Perl Programmers Reference Guide PERLCC(1)NAME
perlcc - generate executables from Perl programs
SYNOPSIS
$ perlcc hello # Compiles into executable 'a.out'
$ perlcc -o hello hello.pl # Compiles into executable 'hello'
$ perlcc -O file # Compiles using the optimised C backend
$ perlcc -B file # Compiles using the bytecode backend
$ perlcc -c file # Creates a C file, 'file.c'
$ perlcc -S -o hello file # Creates a C file, 'file.c',
# then compiles it to executable 'hello'
$ perlcc -c out.c file # Creates a C file, 'out.c' from 'file'
$ perlcc -e 'print q//' # Compiles a one-liner into 'a.out'
$ perlcc -c -e 'print q//' # Creates a C file 'a.out.c'
$ perlcc -I /foo hello # extra headers (notice the space after -I)
$ perlcc -L /foo hello # extra libraries (notice the space after -L)
$ perlcc -r hello # compiles 'hello' into 'a.out', runs 'a.out'.
$ perlcc -r hello a b c # compiles 'hello' into 'a.out', runs 'a.out'.
# with arguments 'a b c'
$ perlcc hello -log c # compiles 'hello' into 'a.out' logs compile
# log into 'c'.
DESCRIPTION
perlcc creates standalone executables from Perl programs, using the code generators provided by the B module. At present, you may either
create executable Perl bytecode, using the "-B" option, or generate and compile C files using the standard and 'optimised' C backends.
The code generated in this way is not guaranteed to work. The whole codegen suite ("perlcc" included) should be considered very experimen-
tal. Use for production purposes is strongly discouraged.
OPTIONS -Llibrary directories
Adds the given directories to the library search path when C code is passed to your C compiler.
-Iinclude directories
Adds the given directories to the include file search path when C code is passed to your C compiler; when using the Perl bytecode
option, adds the given directories to Perl's include path.
-o output file name
Specifies the file name for the final compiled executable.
-c C file name
Create C code only; do not compile to a standalone binary.
-e perl code
Compile a one-liner, much the same as "perl -e '...'"
-S Do not delete generated C code after compilation.
-B Use the Perl bytecode code generator.
-O Use the 'optimised' C code generator. This is more experimental than everything else put together, and the code created is not guaran-
teed to compile in finite time and memory, or indeed, at all.
-v Increase verbosity of output; can be repeated for more verbose output.
-r Run the resulting compiled script after compiling it.
-log
Log the output of compiling to a file rather than to stdout.
