Error Paste many files together side by side

Thank you for your help in advance Smilie.

I have thousands of files like...


I would like to paste every other file side by side so it looks like

file01 file02
file03 file04
file6323 file6324

In addition odd files has the following type of layout:

Preamble(Containing random stuff) (11 lines)

Data Table (11 columns all together) i.e
1 number
2 number
3 number
4 number

In addition even files has the following type of layout:

Preamble(Containing random stuff) (4 lines)

Data Table (columns all together 3) i.e
1 number
2 number
3 number
4 number

essentially joining tables together without the preamble jargon.

Once again thankyou in advance. Cheers Smilie

I am myself a beginner, but a shell script will help



start a counter c = 1:
d = c+1
then Something like
if elif to see even odd files, use sed 11d to clear the preamble or sed 4d depending on condition

then 'paste file${c} file${d}

increment c: c=$((c+1))


Good luck

Use the paste command


while [ $cnt -le 6324 ]
# use files in numeric order
# create odd filename
     fname1=$(printf "file%02d" $cnt)
     cnt=$(( $cnt + 1 ))
#create even filename
     fname2=$(printf "file%02d" $cnt)
     cnt=$(( $cnt + 1))
# remove preamble 11 lines  odd file
     awk ' NR>11 ' $fname1 > /tmp/1
# remove preamble 4 lines  even file
     awk ' NR>4 ' $fname2 > /tmp/2
# put file contents into file with name like "file01file02" ... "file6323file6324"
     paste /tmp/1 /tmp/2 > ${fname1}${fname2}

This does not overwrite the old files, it makes new ones.
