Programming :: Bash: Regexp In 'if' Doesn't Evaluate Correctly
Mar 1, 2011I'm using an 'if' statement to check whether one of positional arguments is a word or a construction like "x-y", but something doesn't seem right.
Here is the relevant part of the code:
Code:
if [[ "$3" =~ [a-Z]-[a-Z] || "$3" =~ [a-Z] ]]; then
grepRange=$3; else grepRange=$4
fi
And for the input like this:
[Code]....
but shouldn't the $grepRange variable be blank in this case?

Programming :: Bash Regexp String Compare Stopped Working?
Oct 20, 2010Have a bash script which contains a line like this:
if [[ ${array[${last}]} =~ "screenpc.PRODUCTION.*" ]]
which WORKED as expected in bash 4.0.33 and now fails in 4.1.2
Instrumented the script to print the value of the left-hand side and it is exactly what is expected.
As noted above, this has been working fine until we installed Fedora 13 (kernel 2.6.33), and now it fails.
Tried setting shell 'extglob' to On with same results.
Did something change? Are there other shell/bash options that need to be set?this has the whole installation stopped!
Ubuntu :: Bash - Open Mlocate Search Results?
Mar 22, 2011Upon a while of searching, I think I failed to find the correct terms and I'm posting here. I often use mlocate to search for files. For example, if I say
Code:
$ mlocate temp_2.pdf
I'll get two results:
Code:
/home/kmc/Documents/latex/temp_2.pdf
/home/kmc/Documents/latex/test/temp_2.pdf
Now if I want to open one of them, I'll have to either open Acroread and browse to their locations. Or select and copy, and call acroread in terminal like
Code:
$ acroread /home/kmc/Documents/latex/temp_2.pdf
This is tedious to me. I'm thinking of a way of quickly open its search results, I've tried pipes like this but it doesn't work:
Code:
$ mlocate temp_2.pdf | acroread
maybe it doesn't work this way. So what does the trick? What's the name of this trick? I've googled for
Quote:
Linux bash catch output, pipe output, open mlocate results And is it possible to handle multiple lines of output, e.g., can I choose which line of output get forwarded to relative programs?

Fedora Installation :: Apt-get Search Wget Saying Invalid Operation Search?
Apr 5, 2011i guess this is an installation issue as i am newish to Linux and got a F14 laptop from a used/refurb store... Anyway it seem i have difficulty with getting GTK running or maybe it is WGET...?
i did manage to install apt-get and was able to run synaptics ... but now whenever i try to run synaptics it flashes the interface and crashes. i tried apt-get search wget and it says invalid operation search. i tried apt cache wget and get a crash box in the upper right corner... i tried apt-get gtk+extra-2.1.2-4.fc14 and it says invalid operation gtk...
All of which is frustrating my attempts to get the GTK interface to J working. Their script uses WGET which i also cannot get.

View 2 Replies View RelatedGeneral :: Use Regexp In Diff / Exclude Lines That Contain The String "[skipthisline]"?
Feb 10, 2011I need to compare 2 files using diff. The problem I've encountered is that I need to exclude certain lines that contain certain phrases. I know that diff supports the -I switch but no matter how I try to form the regexp it doesn't seem to work the way I expect it to. If anyone has used the -I switch before could you please post some examples of how it is used.
diff -I "[skipthisline]" file1 file2 > output.diff
I need to exclude lines that contain the string "[skipthisline]" but I have no idea what syntax is used after the -I switch. Is is supposed to be included in quotes or slashes /[skipthisline]/ or entered without either? I need to include a backslash before each bracket so that it's not interpreted as a set of characters like [a-z] but is instead interpreted as a string. Do I need to use 2 backslashes? "\[skipthisline\]"
Is it sufficient to simply type the string I want to match or do I need to match the entire line in order to exclude it from the output?
.*[skipthisline].*
or
^.*[skipthisline].*$

Programming :: Bash Ctrl+c Tarp And Bash Read With Timeout?

If you remove -t (timeout) option from the read, both loops look the same!

Programming :: Run Multiple Bash And Php Scripts From A Bash Script?
Jul 25, 2011I have written quite a few separate bash & scripts and php scripts that up to now I have run from cron jobs. However I have to estimate how long each takes to run, before running the next and so it probably takes much longer than necessary to run them all. They have to run in order.
Now there are so many I am thinking it would be better to have a master bash script that would run one after the other, but I am not sure how to get the master script to wait before starting to run the next script. Is this possible and is there a command that will make the script wait between bash and php scripts , for them to finish, before running the next?
