Hi all,

I want to get specific pattern from a file content. grep is not working.

file content as follows:
^F^Cã^CÜ^C¾^C·^C\231^C\2226440569gps-input-channel-event-id-out6440568gps-input-channel-event-id-old6440569gps-input-channel-event-id-in


I am interested for the pattern "6440569" only.

Hi,

Assuming that 6440569 is just an example and can be any number, have a look at this: Hope this helps.

actually file content some binary/other character as well and the occurence of this sctring is twice:

^F^Cã^CÜ^C¾^C·^C\231^C\2226440569gps-input-channel-event-id-out6440568gps-input-channel-event-id-old6440569gps-input-channel-event-id-in

Hi,
What kind of file is it? Post the output of the following command: What are you trying to tell me? If they are the same do you want/need them to be shown twice?

Does my provided example show what you need (be it just once)?

Please be a precise as possible when you describe your problem, give a relevant example of the input file and an example of what you want as output.

Hope this helps.

trmusprv:/data/apps/tradem/trmusprv/gps/state# file gps-state-Pvst_US_Sub_GoodRaw_Delim_19.pag
gps-state-Pvst_US_Sub_GoodRaw_Delim_19.pag: data


I tried your command but some how getting error

trmusprv:/data/apps/tradem/trmusprv/gps/state# sed 's/.*event-id-old\(.*\)gps-input-channel.*/\6440569/' gps-state-Pvst_US_Sub_GoodRaw_Delim_19.p
ag
sed: command garbled: s/.*event-id-old\(.*\)gps-input-channel.*/\6440569/trmusprv:/data/apps/tradem/trmusprv/gps/state#

I want to show this once.

thanks for your help on this

I tried this as well

trmusprv:/data/apps/tradem/trmusprv/gps/state# sed 's/.*event-id-old\(.*\)gps-input-channel.*/\1/' gps-state-Pvst_US_Sub_GoodRaw_Delim_19.pag
trmusprv:/data/apps/tradem/trmusprv/gps/state#


no output

Hi,
If this is a partial binary data file then extracting the wanted string might become problematic. Tools like awk, grep and sed work on text files, not binary/data files.

You can try the following: The sed part is a dummy example, without knowing what strings infile spits out I can't give a working sed statement.

If I would assume that the string command outputs something like this: 2226440569gps-input-channel-event-id-out6440568gps-input-channel-event-id-old6440569gps-input-channel-event-id-in, then the following should work; or simpler: Hope this helps.

No output

trmusprv:/data/apps/tradem/trmusprv/gps/state# strings gps-state-Pvst_US_Sub_GoodRaw_Delim_19.pag | sed 's/\(.*\)gps-input-channel.*/\1/'
trmusprv:/data/apps/tradem/trmusprv/gps/state#


No output
trmusprv:/data/apps/tradem/trmusprv/gps/state# strings gps-state-Pvst_US_Sub_GoodRaw_Delim_19.pag | sed 's/.*event-id-old\(.*\)gps-input-channel
.*/\1/'
trmusprv:/data/apps/tradem/trmusprv/gps/state#

Hi,

Instead of telling us there is no output, you might want to post a relevant part of As stated before: The sed part is a dummy example, without knowing what strings infile spits out I can't give a working sed statement.

"gps-state-Pvst_US_Sub_GoodRaw_Delim_19.pag" [Read only] [Incomplete last line] 1 line, 1024 characters (901 null)

Hi,
If not output is generated by using strings then I guess you are out of luck when it comes to the majority of the linux tools, which work with text files and not with data/binary files.

I'm sure C/C++ (higher level programming language) can do this, but I cannot help you with that (besides that: you would also need to know the ins and outs of the generated *.pag files to write a program). Maybe someone else reads this thread and is able to help.
