Combine multiple one column text file into one text file with multiple colum
Hi All. I have multiple text file which contains a one column data. All the data look like this
Code:
1 File 1 Code:
1 Code:
1 Code:
0.495382,0.624025 |
that's too easy
use the read syntax inside a while loop ... See manpage and come back if more help needed |
Thanks for your reply Fantasio.
After googling for some time I finally found the simplest solution to my problem Code:
# paste file1 file2 | sed 's/\t/,/g' I've try to use while loop and read command but my knowledge of shell script is not very good. Can you post the solution using while and read command. I'm curios to see how the solution work. Thank you. |
In fact, I've forgotten that command.
don't know if it works (not tested) while read lig1 <& /tmp/file1.txt ; read lig2 <& /tmp/file2.txt ; do echo $lig1 $lig2; done |
This script work using perl, the previous one contains some mistakes
open FILE1, "/tmp/file1.txt" or die "could not open file1.txt" ; open FILE2, "/tmp/file2.txt" or die "could not open file2.txt" ; open FILE3, "/tmp/file3.txt" or die "could not open file3.txt" ; $file1 = <FILE1>; chomp $file1 ; $file2 = <FILE2>; chomp $file2 ; $file3 = <FILE3>; chomp $file3 ; while ($file1 or $file2 or $file3) { print "$file1 $file2 $file3 \n"; $file1 = <FILE1>; chomp $file1 ; $file2 = <FILE2>; chomp $file2 ; $file3 = <FILE3>; chomp $file3 ; } close FILE1 ; close FILE2 ; close FILE3 ; |
In fact, I've tried to parse file to the standar input but incorrectly, my mind wasn't clear enough
so, if you want read a file to the end with some treatments on it you can do that : while read lig1 ; do echo $lig1 ; done </tmp/file1.txt |
I trapped myself by a too fast answer, but I'm able to give a solution, probably not the best, but this one works and was verified ...
#!/bin/bash let nbline=0 let nbline2=0 let nbline3=0 while read ligne ; do t1[$nbline]=$ligne ; let nbline=$nbline+1 ; done < /tmp/file1.txt ; while read ligne ; do t2[$nbline2]=$ligne ; let nbline2=$nbline2+1 ; done < /tmp/file2.txt ; while read ligne ; do t3[$nbline3]=$ligne ; let nbline3=$nbline3+1 ; done < /tmp/file3.txt ; if [ $nbline2 > $nbline ] ; then let nbline=$nbline2; fi if [ $nbline3 > $nbline ] ; then let nbline=$nbline3; fi for ((l=0;$l<$nbline;l=$l+1)) ; do echo ${t1[$l]} ${t2[$l]} ${t3[$l]} ; done |
thank you
Superb. Thank you for the solution.
