if $1 = "123x456", how can I test for the non-numeric character 'x' in that string. I've tried expr with "" but it did not find the x. Any ideas? Can this perhaps be done with sed?
Thanks. (2 Replies)

During a file-system cleanup I noticed a strange behavior of awk (HP-UX 11iv3 / IA64). When summing up the size of files in one directory it gives different numbers when using print as opposed to printf:
find . -type f -name '*.dmp.Z' -mtime +35 -exec ls -l {} \+ | \
awk 'BEGIN{ OFMT="%f" } {... (1 Reply)

chflags
CHFLAGS(1) BSD General Commands Manual CHFLAGS(1) NAME
chflags -- change file flags SYNOPSIS
chflags [-R [-H | -L | -P]] [-h] flags file ... DESCRIPTION
The chflags utility modifies the file flags of the listed files as specified by the flags operand. The options are as follows: -H If the -R option is specified, symbolic links on the command line are followed. (Symbolic links encountered in the tree traversal are not followed.) -L If the -R option is specified, all symbolic links are followed. -P If the -R option is specified, no symbolic links are followed. -R Change the file flags for the file hierarchies rooted in the files instead of just the files themselves. -h If the file or a file encountered during directory traversal is a symbolic link, the file flags of the link itself is changed. Flags are a comma separated list of keywords. The following keywords are currently defined: Keyword Flag Permission arch archived super-user only opaque opaque owner or super-user nodump nodump owner or super-user sappnd system append-only super-user only schg system immutable super-user only uappnd user append-only owner or super-user uchg user immutable owner or super-user Putting the letters ``no'' before an option causes the flag to be turned off. For example: nouchg the immutable bit should be cleared The -H, -L and -P options are ignored unless the -R option is specified. In addition, these options override each other and the command's actions are determined by the last one specified. The -o option of ls(1) is used to display the flags. The chflags utility exits 0 on success, and >0 if an error occurs. The kernel does not allow the flags on block and character devices to be changed except by the super-user. SEE ALSO
