linux - SCP first line of a file to another system -
i think should possible use combination of scp command , head command copy first line of file remote system, haven't been able come right command make happen.
given scp command this:
scp /shared/myfolder/myfile.txt myuser@myserver:/newlocation/myotherfolder/myfile.txt
i'd send first line of myfile.txt remote system. use command first:
head -1 myfile.txt >> myfile2.txt
and scp myfile2.txt, helpful have in single command.
scp doesn't read stdin or work bash process substitution, can try hacks like:
head -1 myfile.txt | ssh myuser@myserver "cat > /shared/myfolder/myfile.txt"
