I want to view a large text file that is >90gb.  I am using the Tails OS and want to try to do everything from there. I tried vim and sed, but vim crashed because of memory issues and sed didn't seem to do what I needed.  I want to view the file and search for particular parameters to be able to copy and paste that information somewhere else.  Are there any command line tools i can do this with or any tools to download or that already come in Tails that would handle this.  The internal Tails text editor lets me view, but searching doesn't seem to work because of the large file size.

more(1) or less(1), cat(1) does what you need.

[parolsecurity]

cat file.txt | sort -u | grep "your keyword"

[switch-IT]

cat file.txt | sort -u | grep "your keyword"

uniq(1) is faster than GNU sort -u.

$ wc -l file
482447 file
$ sed 5q file
24923
24525
20536
16826
22753
$ time uniq file >/dev/null

real 0m0.027s
user 0m0.027s
sys 0m0.000s
$ time sort -u file >/dev/null

real 0m0.164s
user 0m0.402s
sys 0m0.030s

Not to mention that the command you wrote is useless, merely

grep pattern file

is enough.

I used

grep -i "search parameter" file > "export file"

It works but I want to be able to review the entire file by looking at it to know which search parameters to use and what is actually there that i may not know about yet. I don''t want to split the file, but that may be the best way. Definitely not the fastest.
