Yes, of course, there are other ways to do this, like with pdftk :

pdftk cinq_nostop.pdf burst output cinq_nostop%02d.pdf

Strangely, but luckily, it also works when I ask ghostscript to create...

Hello,

Some googling and checking the man pages told me it should be possible to split a pdf (or ps) file into individual pages :


man gs

You might want to print each page separately. ...

No I don't, because answering "n" to the question immediately expands to "pubmed_result". If one could simply press TAB to get this completion ...

Hello,

Bash completion is great, but there are some features I'd like to change. One thing is the behaviour when there are lots of very similar possibilities.

E.g., my directory contains 133...

Great, thanks !
It would definitely have taken a lot of time before I would have figured out that one can use awk this way ...

Hello

I'd like to remove any line in an output file that is preceded by one or more warning messages (each warning is on a separate line).

Example :
WARNING: Estimation of lower confidence...

the "printf("%d\n",k)" part was my addition ... and indeed, I have no idea of how 32 or 64 bit architectures change that.

But anyway, k was declared as int, so the author of the program should...

Thanks for pointing that out, kermit !
I'll keep that in mind for the next time I analyze large datasets.

jos

[jos@faba ~]$ ulimit -m
unlimited

But you're right, the program is trying to do something ridiculous :


k = com.npatt*com.ncatG*sizeof(double);
if((com.fhK=(double*)realloc(com.fhK,k))...

Hi all

I'm trying to use someone else's software, which has a realloc that fails in it. This is probably due to memory limitations, as it only happens when I use this software on huge datasets.
...

Yes, I know BioPerl exists, I even installed it once.

For the moment, I hardly know perl, and simple tasks like pattern matching, changing file formats, etc are things one can do with awk, sed....

Thanks folks !

Actually, counting is just one of the things I'd like to do frequently ; replacing is another.

I can see quite easily how I could do this using the "fold" command (thanks for...

Hi,

I'm working with DNA sequences, which as you might know are composed of "codons", which are the "words" if you like, and all codons are 3 letters long. So something I frequently need in my...

Merci beaucoup Jean-Pierre !

My gawk-guide wasn't specific enough ... it suggested "0x" instead of "\x", but I guess that's only for hexadecimal to decimal conversions, not for manipulating ascii....

Hi there !

I have text files with some nonsense characters in it, so different text editors put different nonsense symbols, and, worse, the application that should be able to read these files...

Almost !!

Unfortunately, the files can be much more complex : ...

Hi !

I'm looking for a way to transform certain floating point numbers in a one-line, variable length file to integers.

I can do this in a crude way with sed :
sed -e...

Great !

It works, and it's (not surprisingly) much faster than my bc-based solution.
I didn't know that awk could do floating-point arithmetic ... I'm going to learn how to use it right away !
...

Hi there !

I need to treat files with variable line length, and process the tab-delimited words of each line. The tools I know are some basic bash scripting and sed ... I haven't got to python or...

No, I don't, only LC_ALL is not sufficient ... struggled with that yesterday :)

So this seems to work :
alias csort="LC_ALL=C LC_COLLATE=C LC_CTYPE=C sort"I'm not sure why I should create a...

Interesting possibility.
Can one set both LC_COLLATE and LC_ALL this way ?

LC_COLLATE="C" LC_ALL="C" sort ...
??

I found that only setting one of them still leeds to unpredictable sort...

Hi

Don't know if this is a dummy question, but let's give it a try.

I yesterday had a problem with undefined behaviour in the sort shell command (I'm using bash), leading to different sort...

Yes, that one does the job.

I appreciate the awk and perl suggestions of both of you ... they seem more concise than sed, so I'll try get familiar with them soon !

Thanks tyler_durden !

Of course, the solution is two sed commands, which gets rid of a superfluous newline as well ... I told you I was new :-)

This leaves me with the question why [\t ] seems...

Hi !

I'm rather new with sed ... learned a lot already by googling etc ...

The following script should replace all spaces and ends-of-lines with "something (see below).
