Yes that is. With

for line in $(ls); do head -1 $line >> myfile; done

worked as well if I had the files, whose first lines I want to put together, in the same directory, but it is not like this. I've skipped the details. What I wanted is to join together the first value of 6 files named fort.605 in one file, each in a different directory, i.e:


The first way is straightforward, but thanks a lot

globus-update-certificate-dir - Update symlinks in the trusted CA directory SYNOPSIS
globus-update-certificate-dir [-help] [-d DIRECTORY] DESCRIPTION
The globus-update-certificate-dir program creates symlinks between files (CA certificates, certificate revocation lists, signing policy, and certificate request configuration files) using the certificate hash the installed version of OpenSSL uses. OpenSSL 1.0.0 uses a different name hashing algorithm than previous versions, so CA distributions created with older versions of OpenSSL might not be able to locate trusted CAs and related files. Running globus-update-certificate-dir against a trusted CA directory will add symlinks to the files to the hash if needed. The full set of command-line options to globus-update-certificate-dir consists of: -help Display a help message to standard output and exit -d DIRECTORY Create links in the trusted CA directory DIRECTORY instead of using the default search path. ENVIRONMENT
If the following variables affect the execution of globus-update-certificate-dir X509_CERT_DIR Default trusted certificate directory. HOME Path to the current user's home directory. GLOBUS_LOCATION Path to the Globus installation. University of Chicago 02/18/2010 GLOBUS-UPDATE-CERT(8)
